What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is potential energy?

Back

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

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing.

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 type of energy does a roller coaster have at the top of a hill?

Back

A roller coaster has high potential energy at the top of a hill.

Front

What is the relationship between kinetic and potential energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant.

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 does the height of an object affect its potential energy?

Back

The potential energy of an object increases with height, as it is calculated by the formula PE = mgh (mass x gravity x height).

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv² (1/2 x mass x velocity squared).

Front

True or False: Energy can be created or destroyed.

Back

False. Energy cannot be created or destroyed; it can only be transformed from one form to another.
