Kinetic and Potential Energy

Front

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 square of its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in a system.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

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 an example of kinetic energy?

Back

A tennis ball rolling across the court is an example of kinetic energy.

Front

What is an example of potential energy?

Back

A car parked on a steep hill has potential energy due to its elevated position.

Front

What factors affect potential energy?

Back

Potential energy is affected by the height of an object and its mass.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh.

Front

What is the relationship between kinetic and potential energy in a pendulum?

Back

In a pendulum, kinetic energy is highest at the lowest point of the swing, while potential energy is highest at the highest points.
