What is the best way to describe the motion of object B (green)?

• Constant speed, positive slope, and faster than D (red) 
• Moving backwards, toward the origin of where it began 
• Changing its speed (accelerating) 
• Slower than D (red) and constant

In each of the following cases, determine where the car has no acceleration ?

• A car shortly after a stoplight turns green.
• A car approaching a red light
• A car with the cruise control set at 80 km/h
• A car moving down a ramp

What does the slope of a velocity vs. time graph tell us?

• displacement
• velocity
• acceleration
• speed

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

• The object is accelerating.
• The object is not moving.
• The object is decelerating.
• The object is moving at a constant speed.
