AIM• Read a distance versus time

graph

• Calculate velocity

DisplacementDisplacement is the change in

position of an object

Page 3: AIM Read a distance versus time graph Calculate velocity

Displacement

• What is the total displacement in the 100 m dash?

• What is the total displacement if you run from one end of a football field to another?

• What is the total displacement if you run completely around a track stopping at the same place you started?

Page 4: AIM Read a distance versus time graph Calculate velocity

Speed•Speed is the amount of displacement per unit of time.

Equation for speed

Speed

•What is my speed if I travel 10 m in 10 s?

•What is my speed if I travel 100 m in 5 s?

•What is my speed if I travel 42 m in 3 s?

Velocity

•What is my velocity if I travel 10 m north in 10 s?

•What is my velocity if I travel 100 m left in 5 s?

•What is my velocity if I travel 42 m backwards in 3 s?
