Acceleration - Any change in speed or direction Activation energy - the amount of energy needed to start a reaction All objects experience the same acceleration due to - gravity, but only in the absence of air friction Alloys - mixture of metals Alpha decay - a nucleus gives up a helium nucleus Amplitude - The height of the wave, how far you are from the equilibrium Angular Momentum conserved - Angular momentum = Mass * Velocity * Radius Ice Skater ex. As she pulls her arms in, velocity i...
