If an object started moving the the left, what does it mean when its resulting displacement is -5m?

• it ends up 5m to the left

• it ends up 5m to the right

Which among the following is NOT TRUE about the moving object?

• negative displacement means it moved backwards

• negative velocity doesn't mean that it's always moving backwards

• negative acceleration doesn't mean that it's always slowing down

If the acceleration is zero, the man must be standing still.

• TRUE

• FALSE

Velocity and acceleration are always the same sign (both positive or both negative).

• TRUE

• FALSE

If the speed is increasing, the acceleration must be positive.

• TRUE

• FALSE

If you double the initial walking speed, the amount of time it takes to stop....

• is four times longer

• is two times longer

• does not change

• is half as long

A car is moving forward and applying the break. Which position-time graph best depicts this motion?

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 is moving at constant velocity. Then it slows down and stops.

• The ball is moving backwards at a constant velocity. Then it slows down and stops.

• The ball doesn’t move at first. Then it moves backwards and then finally stops.

Draw a velocity-time graph that 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.
