Potential and Kinetic Energy Review

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

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 height and mass.

Front

What factors affect Potential Energy?

Back

Potential Energy depends on mass and height. The higher the object and the more mass it has, the greater its potential energy.

Front

How does mass affect Kinetic Energy?

Back

As mass increases, Kinetic Energy increases, assuming speed remains constant.

Front

What happens to Potential Energy when an object is lifted higher?

Back

When an object is lifted higher, its Potential Energy increases due to the increase in height.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has elastic potential energy.

Front

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Potential Energy?

Back

The formula for Potential Energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

When is Kinetic Energy at its maximum?

Back

Kinetic Energy is at its maximum when an object is moving at its highest speed.

Front

What happens to Kinetic Energy as speed increases?

Back

As speed increases, Kinetic Energy increases exponentially because it is proportional to the square of the speed.
