To apply force toward oneself to move an object closer.

Front

How does surface texture affect friction?

Back

Smoother surfaces have less friction, making it easier to move objects.

Front

What happens when two objects collide?

Back

They exert forces on each other, which can change their motion.

Front

What is the relationship between speed and energy?

Back

Higher speed usually means more energy is involved in the motion.
