Understanding Velocity vs. Time Graphs

What does the slope of a velocity vs. time graph represent?

• Time

• Speed

• Distance

• Acceleration

If an object has a positive velocity and positive acceleration, what is happening to the object?

• It is slowing down.

• It is moving at a constant speed.

• It is stationary.

• It is speeding up.

What happens to an object when it has positive velocity and negative acceleration?

• It moves at a constant speed.

• It stops moving.

• It speeds up.

• It slows down.

What does a negative acceleration indicate about an object's motion?

• The object is stationary.

• The object is slowing down.

• The object is speeding up in the positive direction.

• The object is moving at a constant speed.

In which direction is an object moving if it has negative velocity?

• Stationary

• Rightward

• Leftward

• Upward

What does a negative slope on a velocity vs. time graph indicate?

• Negative acceleration

• Zero velocity

• Positive acceleration

• Constant velocity

What does a flat line on a velocity vs. time graph indicate?

• The object is accelerating.

• The object is decelerating.

• The object is moving at a constant velocity.

• The object is stationary.

What does it mean when an object has zero velocity on a velocity vs. time graph?

• The object is moving at a constant speed.

• The object is stationary.

• The object is decelerating.

• The object is accelerating.

How can you determine the acceleration from a velocity vs. time graph?

• By measuring the length of the line.

• By finding the y-intercept.

• By calculating the slope of the line.

• By measuring the area under the curve.

How is acceleration calculated using the slope of a velocity vs. time graph?

• By dividing the change in velocity by the change in time.

• By multiplying the change in velocity by the change in time.

• By adding the change in velocity to the change in time.

• By subtracting the change in velocity from the change in time.
