Energy Concepts

Front

Potential Energy

Back

The energy an object has because of its position and weight.

Front

Examples of Potential Energy

Back

Roller coaster at its highest point, dam holding and releasing water, apples on a tree, bow and arrow, a slingshot being pulled.

Front

Kinetic Energy

Back

The energy that an object has due to its motion.

Front

Examples of Kinetic Energy

Back

Meteors, walking, falling, throwing a ball, flying airplane.

Front

Formula for Work

Back

Work = Force \times Distance

Front

Formula for Potential Energy (PE)

Back

PE = Weight \times Height

Front

Formula for Kinetic Energy (KE)

Back

KE = \frac{Mass \times Velocity^2}{2}

Front

Formula for Power

Back

Power = \frac{Work}{Time}

Diagram with points A and B

Back

Point A = most potential energy and least kinetic energy. Point B = most kinetic energy and least potential energy.
