Acceleration with a pair of Hot Wheels

  1. Hot Wheels running on a measured track. (The marks are 85 millimeters apart. 76)
  2. Conclusion of race. (Cars are stopped. 77)

Acceleration with a TekBot

  1. Optimus leaves the starting gate and the spring slows the motion to a stop. The marks on the ruler are 85 millimeters apart. (Acceleration with Optimus 99)
  2. Optimus leaves the starting gate and the spring slows the motion to a stop. Camera is panning. (The spring causes acceleration. 100)
  3. Optimus leaves the starting gate and the spring slows the motion to a stop. Camera is still. (101)
  4. The attached spring is stretched. (102)
  5. The wheels slip and Optimus stops. Why? (103)

Algebraic derivations for 'acceleration'. (PPT)

  1. Using "distance equals rate times time" and the definition of acceleration, we arrive at an expression for "Final Velocity". One
  2. Substitute in for 'average velocity' and 'time'; we arrive at 'distance equals one half acceleration times time squared'. Two
  3. The equation involving 'Final Velocity Squared' allows us to use an acceleration expression without using 'time'. Three
