Energy

Introduction to Energy and More

100

Energy of motion

kinetic energy

200

Energy associated with the position of an object and the forces acting on the object

potential energy

300

SI unit of energy

joule

400

This is the relationship between work and energy

Energy is measured by the amount of work that it can do

500

E_P = mgh

The potential energy of an object

Forms of Kinetic Energy

100

Energy exhibited when an object moves and changes positions

translational kinetic energy

200

E_K = 1/2 mv²

kinetic energy of an object

300

Energy exhibited by a spinning wheel

rotational kinetic energy

400

An object that is rotating on an internal axis, like a spinning wheel, is undergoing this type of motion

rotational motion

500

Kinetic energy is affected more by a change in this

speed

Fundamental Forces

100

Strongest fundamental force

AND

Weakest fundamental force

strong nuclear force

gravitational force

200

This fundamental force binds the subatomic particles of an atom's nucleus together

strong nuclear force

300

This fundamental force is responsible for elastic potential energy

electromagnetic force

400

This fundamental force is exerted on all objects that have mass

gravitational force

500

This fundamental force is responsible for most known forces
