Motion Maps

Explain how a motion map can represent the motion of a car moving at constant velocity to the right.

Understanding

What does a longer velocity vector in a motion map indicate about the object's motion?

• The object is moving slower.

• The object is moving faster.

• The object is stationary.

• The object is changing direction.

Analyze the motion map of two cyclists, A and B, where cyclist B overtakes cyclist A at t = 3 s. What can you infer about their velocities?

Analyzing

In a motion map, what does it mean when multiple dots are drawn at the same position?

• The object is accelerating.

• The object is moving at constant velocity.

• The object is stopped.

• The object is moving in reverse.

Understanding

How would you represent an object that moves to the right at constant velocity, stops for two seconds, and then moves to the left at a slower constant velocity on a motion map?

Which of these are key tips to making a motion map?

• Draw dots indicating the position of the object at equal time intervals, i.e. each second.

• Attach arrows to the dots indicating the direction of motion. Make the arrow length half of the

  space between the dots to make your motion map easy to read.

• When an object is stopped for several time intervals, draw multiple dots at the same position.

• Make sure your sequence of arrows has a logical flow so that the motion is clearly communicated

• All of the above
