Questions and Answers

Which of the following correctly defines acceleration?

  • The rate at which an object changes its position
  • The distance traveled divided by the time taken
  • The speed of an object at a particular instant
  • A change in speed or direction in a given time (correct)
  • Which equation can be used to calculate acceleration?

  • $v = s / t$
  • $a = v - u / t$ (correct)
  • $v = u + a t$
  • $a = s / t$
  • What is the difference between speed and velocity?

  • Speed is the rate at which an object changes its position while velocity is the distance traveled divided by the time taken
  • Speed and velocity are the same thing
  • Speed is the distance traveled divided by the time taken while velocity is the rate at which an object changes its position
  • Speed is a scalar quantity while velocity is a vector quantity (correct)
  • What does the equation $v = u + a t$ represent?
