Questions and Answers

What is the mathematical description of position x with respect to time t for linear motion?

  • $x = v + at$
  • $x = at^2$
  • $x = rac{1}{2}at^2$
  • $x = vt$ (correct)

    • Which type of linear motion has constant velocity and zero acceleration?

  • Linear motion with non-zero acceleration
  • Linear motion with variable velocity
  • Non-uniform linear motion
  • Uniform linear motion (correct)

    • According to Newton's first law of motion, what happens to objects that do not experience any net force?

  • Accelerate indefinitely
  • Move in a curved path
  • Continue to move in a straight line with constant velocity (correct)
