What does Kepler’s 2nd law say about planets orbiting the Sun?

Second law A line joining a planet and the Sun sweeps out equal areas during equal intervals of time.

Kepler’s Second Law: the imaginary line joining a planet and the Sun sweeps equal areas of space during equal time intervals as the planet orbits. Basically, that planets do not move with constant speed along their orbits.

What does Kepler’s 2nd law help explain?

Kepler’s second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the Sun. It states that a line between the Sun and the planet sweeps equal areas in equal times. Thus, the speed of the planet increases as it nears the Sun and decreases as it recedes from the Sun.

Kepler’s second law states that a planet sweeps out equal areas in equal times, that is, the area divided by time, called the areal velocity, is constant.

At which part of its orbit is the planet traveling at the slowest speed?

A planet moves with constantly changing speed as it moves about its orbit. The fastest a planet moves is at perihelion (closest) and the slowest is at aphelion (farthest).

What is Kepler’s second law called?

Kepler’s second law ” sometimes referred to as the law of equal areas ” describes the speed at which any given planet will move while orbiting the sun. The speed at which any planet moves through space is constantly changing.

Why Kepler’s 2nd law required that Earth goes slowest at aphelion?

This is because at every moment the planet spends on the perihelion half-ellipse it is closer to the Sun, moving faster; and at every moment it spends on the aphelion half-ellipse it is further from the Sun, moving slower.

Why planets move faster at near region of Sun and slower when they are far away?

When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun’s gravitational pull is weaker, so the planet moves slower in its orbit.

How does gravity result in Kepler’s 2nd law?

Kepler’s Second Law Describes the Way an Object’s Speed Varies along Its Orbit. A planet’s orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves.

How do you apply Kepler’s second law?

Where will an object move at the greatest speed as it orbits the Sun?

The closer an object is to the Sun the faster it needs to move to maintain the orbit. Objects move fastest at perihelion (closest approach to the Sun) and slowest at aphelion (furthest distance from the Sun).

When a planet in its orbit changes its distance from the Sun which of the following remains constant?

Solution : (b) Angular momentum and (e) total energy of the planet, remain constant.

How does the speed of a planet orbit at perihelion as compared to aphelion?

At perihelion, Earth’s distance from the Sun is r=a(1-e) and at aphelion, it’s r=a(1+e). So plugging in the numbers, the speed at perihelion is 30,300 m/s and at aphelion it’s 29,300 m/s.

Which is the slowest orbiting planet?

In fact, Venus takes 243 Earth days to rotate once on its axis ” the slowest rotation of any planet ” and its rotation is retrograde to its orbital path.

Why are higher orbits slower?

The greater the acceleration, the greater the change in velocity ” this causes the object to move faster. This means that objects in small orbits travel faster than objects in large orbits. The graph shows how the orbital speed of a planet changes with its distance from the Sun.

Which of the following planets moves the slowest in its orbit around the sun?

Their speeds vary, but Mercury is the fastest, followed by Venus, Mars, Jupiter, and then Saturn, the slowest. This motion is called direct motion.

Does Jupiter orbit the Sun?

When a planet moves around the Sun its?

The line joining a planet to the Sun sweeps out equal areas in equal interval of time. The rate of change of area with time will be constant. We can see in the above figure, the Sun is located at the focus and the planets revolve around the Sun. That is the aerial velocity of the planets remains constant.

How do planets move around the Sun?

The planets all formed from this spinning disk-shaped cloud, and continued this rotating course around the Sun after they were formed. The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.

What causes Kepler’s 2nd law?

Since the rate of change of angular momentum is zero, that angular momentum must be constant, which then says that the rate of change of swept-out area for the orbit of the celestial body must be constant. This then leads to Kepler’s Second Law, that celestial objects in orbit sweep out equal areas in equal time.

Why do planets move faster at perihelion than at aphelion?

The exact speed changes, because at perihelion, we’re closer to the Sun and feel its gravity a bit more strongly, so our speed around the Sun is a bit faster than at aphelion. Together, the tangential and radial velocities add up to gives us our overall orbital velocity, which changes with distance from the Sun.

At what month is our planet moving the slowest?

Earths orbital velocity is slowest on July 5 because. Revolution. Several might well have moved in closer, or farther out, as the solar system formed.

Why does the speed of a planet decrease as it moves away from the Sun Brainly?

Answer. A planet’s orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun’s gravitational pull, and the slower it moves in its orbit.

Which planet travels around the Sun at the highest speed?

But Mercury is the fastest planet, zipping around the Sun every 88 Earth days.

Which planets move faster around the Sun?

Answer: Mercury is the winner at an orbital speed of about 47.87 km/s (107,082 miles per hour), which is a period of about 87.97 Earth days.

How do the planets move according to Kepler’s laws of planetary motion?

Kepler’s first law means that planets move around the Sun in elliptical orbits. An ellipse is a shape that resembles a flattened circle. How much the circle is flattened is expressed by its eccentricity. The eccentricity is a number between 0 and 1.

Why planets revolve around the Sun in elliptical path?

Why not circular? Orbits are eliptical because of Newtons Law of Gravity (bodies attract each other in proportion to their mass and inversly proportional to the square of the distance between them). All worked out by Kepler some years ago. A circular orbit is a special (and very unlikely) case of an eliptical orbit.

When a planet revolves around the Sun when is its kinetic energy maximum?

Solution : When it is closest to the sun, KE of planet is maximum.

Where will an object move at the greatest speed as it orbits the Sun Quizizz?

Where will an object move at the greatest speed as it orbits the sun? The closer a planet is to the sun, the shorter the orbital period is. The closer a planet is to its star, the lesser its orbital velocity.

What is the orbital speed of Jupiter?

When Earth revolving around the Sun comes near the Sun its speed increases it is based on the?

The angular velocity of the revolution of the planets around the sun increases and this can be explained using Kepler’s second law. It is observed that as the planet gets closer to the sun, the planets move faster because the gravitational pull from the sun get stronger.

When a planet is near its perihelion it is moving faster than when the same planet is near aphelion This is described by?

According the Kepler’s laws of planetary orbits, a planet is moving at its fastest at perihelion. It is moving at its slowest at aphelion. Currently the Earth is at perihelion around 3 January and at aphelion around 3 July.

What is the difference between a planet’s perihelion and aphelion?

Aphelion is the point of the Earth’s orbit that is farthest away from the Sun. Perihelion is the point of the Earth’s orbit that is nearest to the Sun.

Why do planets closer to the Sun move faster?

The closer a planet is to the Sun, the less time it takes for it to go around the Sun. It takes less time because the length of the orbit is shorter (a smaller orbit), but it also moves faster in its orbit. Thanks to gravity, it has to move faster in its orbit to stay in orbit!

Which planet orbits the Sun with the slowest speed?

Slowest Orbital Speed Instead, Neptune again wins with an orbital speed of 12,148 miles per hour. Compared to Earth’s 66,621 miles per hour, Neptune is practically sluggish.

What is the 2nd slowest planet?

Which planet revolves around the Sun in the shortest amount of time?

It only takes 88 days for Mercury to orbit around the sun. No other planet travels around the sun faster.

Why planets move faster at near region of Sun and slower when they are far away?

When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun’s gravitational pull is weaker, so the planet moves slower in its orbit.

When an object in orbit moves too slowly it will?

If it is going slowly, it will not go forward enough to counter the pull of gravity and crash into the thing it is orbiting around. Changing speed is one way to change the orbit of a satellite or make a satellite leave orbit.

How does speed change with altitude of orbit?

The higher the orbit (larger distance between the planet and the satellite), the less speed is required to prevent the satellite from falling out of its orbit and crashing into the planet. The nearer the orbit, the faster it must move to ensure that it does not crash into the planet.

What is Kepler’s second law called?

Kepler’s second law ” sometimes referred to as the law of equal areas ” describes the speed at which any given planet will move while orbiting the sun. The speed at which any planet moves through space is constantly changing.

Which planet rotates most slowly about its axis?

It takes more time for Venus to rotate once about its axis than it takes for the planet to revolve once around the sun. Venus has the slowest period of rotation in the solar system.

How does Jupiter move around the Sun?

However, Jupiter does not technically orbit the sun ” because it’s so dauntingly massive. When a small object orbits a big object in space, the less massive one doesn’t travel in a perfect circle around the larger one. Rather, both objects orbit a combined center of gravity.

Why does Jupiter take longer to orbit the Sun?

Well, the obvious answer is that because it’s further away from the Sun, the longer it takes to make the full trip. And this is right ” the diameter of the orbit Jupiter has to follow to get all the way around the Sun is much greater than ours, which means it takes much longer.

Why did Jupiter move towards the Sun?

According to the new model, Jupiter formed in a region of space about three-and-a-half times as far from the sun as Earth is (3.5 astronomical units). Because a huge amount of gas still swirled around the sun back then, the giant planet got caught in the currents of flowing gas and started to get pulled toward the sun.
