Back

12.8 J.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 0.5 * mass (m) * velocity (v)^2.

Front

What is potential energy?

Back

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

Back

Mass and height above the ground.

Front

What is the unit of energy in the International System of Units (SI)?

Back

Joule (J).

Front

How does height affect potential energy?

Back

Higher objects have more potential energy due to increased height.
