Energy Transformations

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It is often associated with the height of an object above the ground.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, but the total energy remains constant.

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

Give an example of kinetic energy in everyday life.

Back

A wagon rolling down a hill is an example of kinetic energy.

Front

What is the relationship between height and potential energy?

Back

The higher an object is positioned, the greater its potential energy due to the gravitational force acting on it.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed; if the speed doubles, the kinetic energy increases by four times.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.

Front

What is an example of energy transformation?

Back

When a roller coaster goes down a hill, potential energy is transformed into kinetic energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.
