The area under a velocity time graph is the ________.
Displacement.
Can a car traveling on an interstate highway have a negative velocity and a positive acceleration at the same time? Explain.
Yes, a car's velocity is positive or negative with respect to its direction of motion from some point of reference. A positive acceleration with a negative velocity would imply the car is traveling in the negative direction and slowing down.
Acceleration describes a change in ________.
Velocity.
