Potential & Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. For example, a rock at the edge of a cliff has potential energy.

Front

What happens to Kinetic Energy when an object speeds up?

Back

As an object speeds up, its kinetic energy increases.

Front

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

Back

As an object is lifted higher, its potential energy increases.

Front

Can an object have both Kinetic and Potential Energy at the same time?

Back

Yes, an object can have both types of energy. For example, a swinging pendulum has kinetic energy at its lowest point and potential energy at its highest point.

Front

What is an example of Kinetic Energy in everyday life?

Back

An example of kinetic energy is a moving car or a running dog.

Front

What is an example of Potential Energy in everyday life?

Back

An example of potential energy is a stretched rubber band or a book on a shelf.

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

How is Potential Energy calculated?

Back

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