A merry-go-round moves in a circle at a constant speed. Is the merry-go-round accelerating? Explain your answer.
Yes, the merrygoround is accelerating. Although the speed remains constant, acceleration is defined as a change in velocity, which includes both speed and direction. Since the merrygoround moves in a circle, its direction is constantly changing, meaning it is accelerating.

A car traveling at a speed of 24 m/s comes to a stop at a red light.How much time will it take for the car to stop if its acceleration is –8.0 m/s2?
The graph shows the motion of a car. Which segments show that the car is accelerating? Select three options.
[___] m/s

What is the acceleration of the car at segment C?
Maia says that both lines on this position vs time graph show acceleration. Is she correct? Why or why not?
No. Only the blue curved line shows acceleration because its slope (velocity) increases over time. The orange straight line has a constant slope, so it shows constant velocity and no acceleration.
