kinetic energy (KE) energy an object possess through motion, measured in Joules (J)
Formula for calculating Kinetic Energy K.E. = 1/2 Mass x Speed ^2
potential energy (PE) stored energy that can transform into kinetic energy
gravitational potential energy (GPE) objects vertical position above ground, measured in Joules (J)
Formula for calculating Gravitational Potential Energy (GPE) GPE= Weight x height above ground
