Constant Velocity Graphs Quiz

What does the slope of a position vs. time graph represent in physics?

• Acceleration

• Velocity

• Distance

• Time

Which of the following best describes the motion of an object if its velocity vs. time graph is a horizontal line above the time axis?

• The object is at rest.

• The object is moving at a constant velocity.

• The object is accelerating.

• The object is moving backward.

Which of the following is true for an object moving with constant velocity?

• The acceleration is zero.

• The position changes at a non-uniform rate.

• The velocity changes over time.

• The object must be at rest.

A position vs. time graph shows a straight line sloping upward to the right. What does this indicate about the object's motion?

• The object is slowing down.

• The object is moving at a constant positive velocity.

• The object is moving at a constant negative velocity.

• The object is not moving.

Given a position vs. time graph, how would you determine the velocity of the object?

• Measure the area under the graph.

• Find the slope of the graph.

• Find the y-intercept of the graph.

• Count the number of data points.

• The object is moving forward at a constant speed.

• The object is moving backward at a constant speed.

• The object is accelerating.

• The object is at rest.

Which of the following position vs. time graphs represents an object moving at the fastest constant velocity?

• A horizontal line
