If a velocity versus time graph shows a straight line with a positive slope, what does this indicate about the object's motion?

• The object is moving at a constant velocity.

• The object is at rest.

• The object is undergoing constant positive acceleration.

• The object is moving backward.

What information about an object's motion cannot be determined directly from a velocity versus time graph?

• Its acceleration.

• Its change in velocity.

• Its initial position.

• Its change in time.

On a velocity-time graph, what does a line above the time axis indicate about the object's motion?

• Moving to the right

• Moving to the left

• Stationary

• Accelerating

What does the slope of a position versus time graph represent?
