Velocity - How fast something is moving. Units = m/s, Time - How long something takes. Units = s, Distance - How far something has travelled. Units = m, Acceleration - Change in speed over time. Units = m/s2, Force - A push or a pull. Units = N, Mass - How much matter makes up something. Units = kg, Energy - Allows something to do work. Units = Joules, Power - How much energy is spent over time. Units = Joules, Work - How much energy is spent/gained by an object. Unit = Joules, Kinetic Energy - Energy that moving objects have, Gravitational Potential Energy - Energy that objects up high have before they fall, Friction - A force that slows something down while it's moving,
