Potential/Kinetic Energy

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is the definition of potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. It has the potential to do work when released.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the formula for calculating potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What unit is used to measure energy?

Back

Energy is measured in Joules (J).

Front

What is the relationship between potential energy and height?

Back

Potential energy increases as the height of an object increases, assuming mass and gravity remain constant.

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 an example of kinetic energy in everyday life?

Back

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

Front

What is an example of potential energy in everyday life?

Back

A drawn bow, a book on a shelf, or water stored in a dam are all examples of potential energy.

Front

How does mass affect kinetic energy?

Back

The greater the mass of an object, the greater its kinetic energy at a given speed.
