Gravity Review

What happens to the weight of an object if it is moved from Earth to the Moon?

• It increases because the Moon is smaller.

• It stays the same because the object's mass doesn't change.

• It decreases because the Moon's gravity is weaker.

• It disappears because there is no gravity on the Moon.

Why do astronauts float inside the International Space Station (ISS)?

• Because there is no gravity in space.

• Because the ISS is moving at a constant speed.

• Because the gravity is much weaker in space, creating a microgravity environment.

• Because they are moving in the opposite direction of Earth's gravitational pull.

What would happen to an object's weight if it were moved from Earth to Jupiter?

• It would decrease because Jupiter is farther from the Sun.

• It would stay the same because the object's mass doesn't change.

• It would increase because Jupiter's gravity is stronger.

• It would disappear because Jupiter is a gas giant.

How does gravity affect the orbit of the Earth around the Sun?

• Gravity pushes the Earth away from the Sun.

• Gravity has no effect on Earth's orbit.

• Gravity pulls the Earth towards the Sun, keeping it in orbit.

• Gravity slows down the Earth's orbit around the Sun.

What is the role of gravity in the formation of tides on Earth?

• Gravity from the Sun and Moon pulls on Earth's oceans, creating tides.

• Gravity inside the Earth pushes water towards the surface, creating tides.

• Gravity from the Earth pulls the Moon closer, causing tides.

• Gravity has no role in the formation of tides.

If you were to jump on Mars, compared to Earth, you would:

• Jump higher because Mars has weaker gravity.

• Jump the same height because your muscles are the same.

• Jump lower because Mars has stronger gravity.

• Not be able to jump because there is no gravity on Mars.

Why do planets orbit the Sun in an elliptical shape rather than a perfect circle?

• Because the Sun's gravity pulls them closer at certain points in their orbit.

• Because the planets are trying to escape the Sun's gravity.

• Because the gravitational pull is the same at all points in their orbit.

• Because the Sun moves through space, altering the planets' paths.

What would happen to the Earth if the Sun's gravity suddenly disappeared?

• Earth would continue to orbit the Sun as before.

• Earth would fly off into space in a straight line.

• Earth would move closer to the Sun.

• Earth would stop moving altogether.

How does gravity help planets stay in orbit around the Sun?

• By pushing the planets away from the Sun.

• By pulling the planets towards the Sun with a force that balances their tendency to move in a straight line.

• By increasing the speed of the planets as they get closer to the Sun.

• By decreasing the mass of the planets, making them lighter.

What effect does gravity have on the time it takes for a planet to orbit the Sun?

• The stronger the gravity, the longer it takes for a planet to orbit the Sun.

• Gravity has no effect on the time it takes for a planet to orbit the Sun.

• The stronger the gravity, the shorter it takes for a planet to orbit the Sun.

• The time it takes for a planet to orbit the Sun is only determined by its distance from the Sun, not gravity.
