Motion Test

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

A runner races in the 100 meter dash.  It takes her 10 seconds to finish.  What is her average speed?

• 10 m/s
• 1000 m/s
• 100 seconds

What is the speed of an object that travels 60 meters in 4 seconds?

• 240 m/s
• 15 m/s
• 0.067 m/s

• A chair

• A moving child

• the flag pole

What is this graph showing?

• Constant Speed

• Acceleration (speeding up)
