The Law of Conservation of Energy
Energy can neither be created nor destroyed, only transformed.
Definition of POTENTIAL ENERGY
What is stored energy?
Newton's second law
F=m x a
Mass
Kilograms (kg)
A light bulb converts electrical energy into these 2 types of energy
What is heat/thermal and light/electromagnetic?
Newton's first law
An object at rest remains at rest. An object in motion remains in motion at a constant velocity unless acted upon by an unacted force.
Definition of FORCE
A push or pull between 2 or more objects
Velocity formula
V=d/t or velocity equals distance divided by time
Acceleration
meters/second squared (m/s2)
