What is the equation to calculate speed?

• speed = distance/time
• speed = time/distance
• speed = time x distance 
• speed = speed/time 

What is the equation to calculate time?

• time = speed/distance
• time = distance/speed 
• time = speed x distance 
• time = distance x speed

What is the equation to calculate distance?

• distance = speed/time
• distance = time/speed
• distance = speed/distance
• distance = speed x time 

What is happening in this graph from point A to B?

• The object is accelerating (speeding up)

• The object is changing direction

• The object is accelerating (slowing down)

• The object is moving at a constant speed.

What is happening in this graph from point B to C?

• The object is going down a hill.

• The object is returning to its starting location.

• The object is slowing down.

• The object is staying still.

What does this graph represent?

• Constant Speed
• Acceleration
• Not moving

How long did it take this object to travel 10 m?

• 0 s
• 10 s
• 15 s
• 20 s

When a car goes around a corner at 20 mph, why do we say it  accelerates?

• The car is accelerating because of the velocity is constant
• The car accelerates because it's going 20 mph
• Cars always accelerate when they are in motion
• The car is accelerating because it's changing direction
