What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that has the potential to be converted into kinetic energy.

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

What is gravitational energy?

Back

Gravitational energy is a form of potential energy that depends on the height of an object above the ground. The higher the object, the more gravitational energy it has.

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

How does an electric current affect a compass?

Back

An electric current creates a magnetic field around the wire, which can cause the compass needle to move.

What is the relationship between mass and gravitational force?

Back

The gravitational force between two objects increases with the mass of the objects and decreases with the square of the distance between them.

What is the principle of conservation of energy?

Back

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

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact.
