Kinectic and Potential Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object when it is in motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

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 happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

At which point does a pendulum have maximum potential energy?

Back

A pendulum has maximum potential energy at its highest points (extremes of the swing).

Front

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

Back

In a roller coaster, potential energy is highest at the top of the hills, and kinetic energy is highest at the lowest points.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car, a running dog, or a flowing river are all examples of kinetic energy.

Front

What is an example of potential energy in everyday life?

Back

A book on a shelf, a stretched rubber band, or water behind a dam are examples of potential energy.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; if mass doubles, kinetic energy also doubles if velocity remains constant.

Front

How does velocity affect kinetic energy?

Back

Kinetic energy increases with the square of velocity; if velocity doubles, kinetic energy increases by four times.
