Energy

Front

What is thermal energy?

Back

The total kinetic and potential energy of the particles in an object.

Front

What does an object's potential energy depend on?

Back

An object's potential energy depends on its weight and its height.

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is work in terms of energy?

Back

Work is the transfer of energy that occurs when a force is applied over a distance.

Front

What type of energy is produced when an object vibrates?

Back

Sound energy is produced when an object or substance vibrates.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

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

Front

How is gravitational potential energy calculated?

Back

Gravitational potential energy is calculated using the formula: PE = mgh (mass x gravity x height).

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object.
