Force, Gravity, Friction, Work

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It makes it harder for things to slide past each other.

Front

What does gravity do?

Back

Gravity is a force that pulls objects toward each other. It keeps us on the ground and makes things fall.

Work is done when a force moves an object. If nothing moves, no work is done.

Front

What is a lubricant?

Back

A lubricant is a substance that reduces friction between surfaces, making it easier for them to move.

Front

What happens when there is less friction?

Back

When there is less friction, objects can move faster and more easily.

Front

Can gravity change?

Back

Gravity is a constant force on Earth, but it can change depending on where you are in the universe.
