Motion Whodunnit?

How is average speed calculated?

Accelertion changes when there is a change in ​ (a)  

• velocity
• speed
• time
• position

Speed measures ​ (a)  

• how fast an object is moving.
• how far away an object is.
• how high up an o object is.n
• how heavy an object is.

The defference between speed & velocity is that velocity also includes a ​ (a)  

• direction
• distance
• time
• height
