On a velocity vs. time graph, what does the area under the curve represent?

• Acceleration

• Displacement

• Distance

• Velocity

A ball is thrown straight up. At the highest point of its motion:

• Velocity and acceleration are both zero

• Velocity is zero, but acceleration is not

• Acceleration is zero, but velocity is not

• Velocity and acceleration are both nonzero

Which of the following indicates an object is slowing down on a velocity vs. time graph?

• Positive slope

• Negative slope

• Slope of zero

• Velocity and acceleration in opposite directions

If an object is accelerating but has zero velocity at a moment in time, then:

• It must be turning around

• It must be at rest

• It must be falling

• It is not accelerating

A motion sensor records a position-time graph with a straight line sloping upward. What is true of the motion?

• Velocity is constant and positive

• Acceleration is constant

• Speed is decreasing

• Object is stationary

On a velocity vs. time graph, an object with a negative velocity and positive acceleration is:

• Speeding up in the positive direction

• Slowing down

• Moving at constant speed

• At rest

What does a curved position-time graph indicate about an object’s motion?

• The object is at rest

• The object has constant speed

• The object has constant velocity

• The object has changing velocity

Two cars start at the same time and same position. Car A moves with constant speed. Car B starts from rest and accelerates. Which statement is true?

• Car A is always ahead

• Car B is always ahead

• Car B eventually passes Car A

• Both arrive at the same time
