What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as light, sound, heat, and motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a drawn bow has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

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

Can kinetic energy be converted to potential energy?

Back

Yes, kinetic energy can be converted to potential energy, such as when a roller coaster climbs a hill.

Front

What is the relationship between kinetic energy and mass?

Back

The relationship is linear; as mass increases, kinetic energy increases if speed remains constant.

Front

What is the relationship between kinetic energy and speed?

Back

The relationship is parabolic; as speed increases, kinetic energy increases exponentially.

Front

What happens to potential energy when an object falls?

Back

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

Front

What is an example of potential energy?

Back

A rock held at the top of a hill has potential energy due to its height.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy due to its motion.
