Speed Velocity and Acceleration Quiz

Example Questions From the Test

• 1An object's acceleration is zero over a time interval. What can be concluded about its velocity during that interval?
  • Its velocity must be zero.
  • Its direction must change while its speed stays constant.
  • Its speed must decrease at a constant rate.
  • Its velocity remains constant, though it may be zero or nonzero.
• 4A velocity-time graph shows a horizontal line at 8 m/s. What does this indicate?
  • The object is stationary and has constant acceleration.
  • The object travels 8 meters in total.
  • The object has constant velocity and zero acceleration.
  • The object's velocity increases by 8 m/s each second.
• 5What does the signed area between a velocity-time graph and the time axis represent?
  • Average acceleration
  • Final speed
  • Displacement
  • Total elapsed time
