Acceleration • Definition • A body accelerates when it changes speed or direction or both. Average acceleration • is defined as the change in velocity divided by the time elapsed during the change in • velocity • Positive and Negative Acceleration • Text Page 44
Uniform Acceleration • Four Equations for Uniform Acceleration
Falling Bodies • Acceleration Due to Gravity – Free Fall • 9.80 m/s2 Using the diagram to your right, you need to be able to: 1. explain why acceleration is uniform 2. describe why velocity changes 3. graph the motion of the ball in a velocity time graph Text pages 50 - 51
