Kinetic and Potential Energy

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 square of its velocity.

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.

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy. This is because potential energy is calculated as PE = mgh (mass x gravity x height).

Front

What happens to potential energy when an object is lifted?

Back

When an object is lifted, its potential energy increases because its height above the ground increases.

What happens to kinetic energy when an object's speed increases?

Back

As an object's speed increases, its kinetic energy increases. Kinetic energy is calculated as KE = 1/2 mv² (1/2 x mass x velocity squared).

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

Back

In a bouncing ball, potential energy is converted to kinetic energy as it falls, and kinetic energy is converted back to potential energy as it rises.

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.

How does mass affect kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object. A heavier object moving at the same speed has more kinetic energy than a lighter object.

What is an example of potential energy?

Back

An example of potential energy is a book placed on a shelf. It has potential energy due to its height above the ground.
