    Acceleration
  •   Study   Slideshow
  • The change in velocity in on second
    Acceleration
  •  15
  • Sometimes a body moves with has zero acceleration.
    Because this body moves with constant velocity
  •  15
  • This body has an acceleration or zero acceleration and why ?
    has an acceleration because it has a changing velocity
  •  15
  • The unit of measuring acceleration is .............................
    m/s2 or Km/h2
  •  15
  • initial v = 5 m/s, final v = 0 m/s, time is 20 seconds, what is a (acceleration)                                   a-(0-5)/20         b-(5-0)/20               c-5/20                 d-20/(5-0)
    a-(0-5)/20

  • True or False : Acceleration only takes place when things speed up.
    False

  • Acceleration is defined as the CHANGE in ....................... time of motion to another place.            a- velocity           b-distance              c-speed
    Velocity

  • Changes in our speed, direction or both are called _________.    a-gravity       b-changes                c-acceleration
    acceleration

  • When are you undergoing an acceleration in a car?                  a-speed up     b- slow down     c-make turns     d-All of the above
    d-All of the above
  •  15
  • 4-Determine the motion of the car.      A-at rest      b-speeding up     C-moving at constant speed    D-slowing down
    b-speeding up
  •  15
  • 3-Acceleration is defined at a change in velocity. Velocity is ______      A-Speed and direction      B-The same thing as speed       C-distance/time       D-time/distance 
    A-Speed and direction

  • . A car accelerates from a standstill to 70 m/s in 10 seconds. What is the acceleration?    a-0.7m/s2     b-7m/s2     c-14m/s2     d-none of the above 
    7m/s2
