Module 2

• Change in position of an object. Displacement
• velocity at a specific instant of time. Instantaneous Velocity
• rate which velocity changes. Acceleration
• displacement divided by the time of travel. Average velocity
• acceleration at a specific instant of time. Instantaneous Accelerator
• Average velocity. displacement/Time interval
• Acceleration of gravity. g=9.8 m/s2
• positive sign in downward motion and negative if upward motion
