joule SI unit for energy (and work)
transformation change
kinetic energy energy of motion (part of mechanical energy) KE + PE = mechanical
potential energy energy of position (part of mechanical energy) KE + PE = mechanical
gravitational potential energy same as Potential Energy- just referenced to its position above the earth; higher up it is, the more gravitational potential energy it has
law of conservation of energy energy cannot be created nor destroyed; only changed or transformed into another form
reference point place or object you are comparing motion to
motion going from one point or position to another
magnitude strength
vector direction
speed the rate at which motion occurs- distance compared to time; d/t
velocity speed with direction
