Front

What is acceleration?

Back

Acceleration is when an object is getting faster.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.
