Kinematics Graphs

Below is a graph of a ball’s motion. Which of the following gives the best interpretation of the ball’s motion?

• The ball moves along a flat surface. Then it

  moves forward down a hill, and then finally stops.

• The ball doesn’t move at first. Then it moves forward

  down a hill and finally stops.

• The ball is moving at constant velocity. Then it

  slows down and stops.

• The ball doesn’t move at first. Then it moves

  backwards and then finally stops.

• The ball moves along a flat area, moves backwards

  down a hill and then it keeps moving.

Which graph would best depict the following scenario? A man starts at the origin, walks back slowly and steadily for 6 seconds. Then he stands still for 6 seconds, then walks forward steadily about twice as fast for 6 seconds. Note that these are velocity-time graphs.
