Newman's Physics Review

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, and it exists between all objects in space.

Front

What effect does gravity have on planets?

Back

Gravity causes planets to orbit around the Sun.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when one object exerts more force than another, causing a change in motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

What causes a bowling ball to stop faster on a carpet than on a tile floor?

Back

Friction between the bowling ball and the carpet is greater than on the tile floor.

Front

What is the gravitational pull of Earth?

Back

The gravitational pull of Earth is the force that pulls objects towards the center of the Earth.

Front

What happens when two forces are balanced?

Back

When two forces are balanced, they cancel each other out, and there is no change in motion.

Front

How does air resistance affect falling objects?

Back

Air resistance slows down the motion of falling objects, but gravity pulls them towards the ground.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What is an example of a force that can change an object's speed?

Back

An unbalanced force, such as a dog pulling on a rope, can change an object's speed.
