Energy Review

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What factors does potential energy depend on?

Back

Potential energy depends on the height and weight (mass) of the object.

Front

What type of energy is stored in food?

Back

Chemical potential energy is stored in food and is released when the food is consumed and metabolized.

Front

How is energy measured?

Back

Energy is measured in joules.

Front

What are the two types of energy used by an electric heater?

Back

Electric and Thermal energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and speed.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.
