Potential and Kinetic 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 its velocity.

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.

Front

What is Gravitational Potential Energy?

Back

Gravitational potential energy is the energy an object has due to its height above the ground and is calculated as PE = mgh (mass x gravity x height).

Front

How does energy transfer occur?

Back

Energy transfer occurs when energy moves from one object or system to another, often through work or heat.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa. For example, when an object falls, its potential energy decreases while its kinetic energy increases.

Front

What factors affect Kinetic Energy?

Back

Kinetic energy is affected by the mass of the object and its velocity. Doubling the mass or the velocity increases the kinetic energy.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a flowing river, or a spinning windmill blade are all examples of kinetic energy.

Front

What is an example of Potential Energy in everyday life?

Back

A rock at the edge of a cliff, a stretched rubber band, or water stored in a dam are all examples of potential energy.

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 formula for calculating Kinetic Energy?

Back

The formula for kinetic energy is KE = 1/2 mv² (where m is mass and v is velocity).
