The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down. 

What is the formula to calculate speed?

• S = t/d
• S = d/t
• S = d x t
• S = t x d

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object
