Mass is a measure of matter in an object. Measured in kg.

Define Weight

Weight is a measure of the gravitational force to which an object is attracted. It changes relative to the position in the universe. Measured in Newtons (N)

What is the formula for Universal Gravitational Force

FG= GM1M2÷d1,2²

Define Gravitational Potential Energy

GPE (Ep or U) is the energy stored by doing work against the force of gravity, is given by FG × d

Formula for Gravitational Potential Energy

-GM1M2/d

Total Energy of System =

Et = Ek + Ep
