Physics Motion Graph Quizizz 2022

Which line represents an object moving at a faster speed?

• A
• B

This graph demonstrates an object that is -

• At a constant speed
• Increasing speed
• Decreasing speed
• Stationary

What is the formula for speed?

• speed = distance x time

• speed=distance / time

• speed = time / distance

• speed = distance + time

Select the description of motion from A - B.

• Slowing down away from the origin

• Speeding up away from the origin

• Constant velocity away from the origin

• Constant velocity towards the origin

Part A of the graph is from 0s to 25s. Which of these statements is true about Part A?

• The object is at rest.

• The object is accelerating (its velocity is increasing)

• The object is decelerating (its velocity is decreasing)

• The object is moving at a constant velocity.

Part B of the graph is from 25s to 35s. Which of these statements is true about Part B?

• The object is at rest.

• The object is accelerating (its velocity is increasing)

• The object is decelerating (its velocity is decreasing)

• The object is moving at a constant velocity.

Part C of the graph is from 35s to 55s. Which of these statements is true about Part C?

• The object is at rest.

• The object is accelerating and speeding up (its velocity is becoming more positive)

• The object is accelerating and slowing down (its velocity is becoming more negative and heading towards 0 m/s)

• The object is moving at a constant velocity.

What does a flat (horizontal) line on a velocity-time graph mean?

[Example section B on this graph]

• The object is not moving.

• The object is moving, but at a constant velocity.

• The object is accelerating, and its acceleration is positive.

• The object is accelerating, and its acceleration is negative.

• 5.5 s

• 7.0 s

The position-time graph of two runners A and B is given. When does runner B pass runner A?

• 40 s

• 35 s

• 45 s

• 50 s
