Lesson 0.2: Uniform Accelerated Motion

Cards (8)

  • If a body maintains a constant change in its velocity in a given time interval along a straight line, then the body is said to have a Uniform Acceleration.
  • Equation A: v=d/t
  • Equation B: vave = vf-vi/2
  • Equation C: a = vf-vi/t
  • where:
    • v = velocity
    • vf = final velocity
    • vi = initial velocity
    • vave = average velocity
    • d = displacement
    • t = time
    • a = acceleration
  • Equation D: d = (vf + vi/2)t
  • To find out how displacement changes with time when an object is uniformly accelerated, rearrange equation A to arrive at d = vt. Since the velocity of the object changes when it is uniformly accelerating, we use the average velocity to determine displacement, so substituting v by Vave in equation B
  • Equation E: d = vit + at^2/2
