Back

Friction is a force that opposes motion between two surfaces.

Front

How does gravity affect motion?

Back

Gravity pulls objects towards the Earth, affecting their motion.

Front

What is a pendulum?

Back

A pendulum is a weight hung from a fixed point that swings back and forth.

Front

What happens when friction is reduced?

Back

When friction is reduced, objects can move more easily.
