Describing motion
Motion is a change in position
Relative Motion
Speed = Distance / Time S = d/t
Calculating Speed
Position can change at different rates
Speed measure how fast a position changes
Average speed
Distance time graphs
Velocity
Velocity includes speed and direction
Velocity includes speed and direction
Velocity Versus Speed
Speed and direction can change with time
Acceleration measures how fast velocity changes
Acceleration can be calculated from velocity and time
