What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, an apple on a table has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What happens to energy when an apple falls from a table?

Back

The energy transforms from potential energy to kinetic energy as it falls, and then to sound energy when it hits the floor.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from potential energy to kinetic energy.

Front

What is energy transfer?

Back

Energy transfer is the movement of energy from one object to another, such as when heat moves from a hot object to a cooler one.

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 work in physics?

Back

Work is defined as the force applied to an object multiplied by the distance the object moves in the direction of the force.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It is a form of kinetic energy.

Front

What is an example of kinetic energy transforming into thermal energy?

Back

When a train moves at high speed, friction between the train and the tracks generates heat, transforming kinetic energy into thermal energy.
