Constant Velocity

The speedometer on your car tells you

• average velocity
• instantaneous velocity
• average speed
• instantaneous speed

What is this graph representing?

• Constant Speed
• Acceleration (speeding up)
• Deceleration (slowing down)
• No motion

• Graph A
• Graph B
• Graph C
• Graph D

Which of the graphs shows that one of runners started 10 yards further ahead of the other (note that graph c is the bottom right and graph d is the bottom left)? 

• Graph A
• Graph B
• Graph C
• Graph D
