Gravity

Front

What is gravity?

Back

The force that pulls everything toward the ground

Front

Who was the first person to study gravity?

Back

Isaac Newton

Front

What happens to objects when they get closer to the Moon?

Back

They get pulled toward the Moon

Front

What is the effect of air resistance on falling objects?

Back

It makes objects fall slower

Front

What did the experiment with the feather and hammer on the Moon show?

Back

Feathers and hammers fall at the same rate on the Moon

Front

What is the force that keeps objects from flying off the surface of the Earth?

Back

Gravity

Front

What is the effect of distance on the pull of gravity between objects?

Back

The closer objects are, the stronger the pull of gravity

Front

The gravitational attraction between two objects would increase if both masses are –

• increased, and the distance between them is increased.
• increased, and the distance between them is decreased.
• decreased, and the distance between them is decreased.
• decreased, and the distance between them is increased.

Back

increased, and the distance between them is decreased.

Front

Why do planets orbit the Sun?

Back

The Sun is the most massive object in our solar system, so it exerts the greatest gravitational pull.

Front

As distance between two objects increases, the pull of gravity

Back

decreases.
