Science 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!

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​

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 ​

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^​
