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 can be gravitational, elastic, or chemical energy.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height of the object above the ground and its mass.

Front

If two objects are at the same height, which has more potential energy?

Back

The object with the greater mass has more potential energy.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula is PE = mgh, where PE is potential energy, m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the relationship between kinetic energy and speed?

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.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the principle of conservation of energy?

Back

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

Front

What type of energy does a stretched slingshot have?

Back

A stretched slingshot has potential energy due to its position.
