Front

What type of energy does a rolling boulder have as it crashes down a mountain?

Back

Kinetic energy.

Front

How do you calculate potential energy?

Back

Potential energy (PE) = mass (m) × gravity (g) × height (h).

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 × mass (m) × velocity (v)².

Front

What happens to potential energy as an object falls?

Back

It is converted into kinetic energy.
