What is Energy?

How Do We Define Energy?

Energy is the ability to cause a change. It also defined as the ability to do work!

​

Work is done when a force moves an object through a distance. This energy is primarily measured in Joules. ​

Walking around the class uses energy, which is measured in Joules!

What is Energy?

Two Types of Energy

Kinetic Energy is defined as the energy of motion; of objects, waves, electrons, atoms, molecules, and other substances.

​

The more mass an object has, the more kinetic energy it has.

The equation is as follows: KE = 1/2mv^2​

What is Energy

Two Types of Energy

Potential Energy is energy that is stored and held in readiness. Energy can be stored due to an object's change in shape, position, or chemical composition.

​

Example: When you raise a book up high, you give the object potential energy ​

What is Energy?

Gravities Effect on Energy

Gravitational potential energy depends on the height of the object above the Earth.

​

Any object near Earth's gravitational pull, is affected by 9.8 m/s²

The Equation Is: GPE = mgh^​
