Question

The figure shows the graphs of three functions. One is the position function of a car, one is the velocity of the car, one is its acceleration, and one is its twitch. Identify each curve.

Answer 1

a) Is the twitch - initial positive twitch or sudden movement, which is what makes the car jolt into action.

b) is the acceleration - graph shows the acceleration and deceleration of the car.

c) is the velocity - starts at 0 and increases until the car travels at its right speed.

d) is the position - assuming that the car is going on only one direction. This graph is the only one that does not go back to the x-axis.
