Potential and Kinetic Energy

Front

Energy due to motion is ____________ energy.

Back

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

Front

__________ is stored energy.

Back

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

Front

Calculate the potential energy of a car with a mass of 2,500 kg that is on a hill 100 meters above sea level.

Back

Potential Energy (PE) = mass (m) × gravity (g) × height (h) = 2,500 kg × 9.8 m/s² × 100 m = 2,450,000 J.

Front

The faster an object moves, the ________ kinetic energy it has.

Back

The faster an object moves, the more kinetic energy it has.

Front

When mass increases, what happens to the energy (both potential AND kinetic)?

Back

When mass increases, both potential and kinetic energy increase.

Front

What is the formula for calculating potential energy?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

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

Front

If an object is at rest, what type of energy does it have?

Back

An object at rest has potential energy, but no kinetic energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.
