Purpose:

The purpose of this lab was to calculate coefficient of rolling friction of a cart along a ramp using the theoretical acceleration using Newton’s 2nd Law and experimental acceleration using ticker-tape data analysis.

Materials:

  • Ticker-tape timer
  • Ticker-tape
  • Transparent tape
  • 0.839kg Cart with three wheels
  • 0.500kg weight
  • 0.200kg weight
  • A ramp approximately 2 m in length with a pulley attached at the end
  • Ruler – 1m
  • Two desks (labeled 1,2 according to the diagram)
  • 1 Approximately 2m long string

Diagram of Apparatus:

Procedure:

  1. The apparatus was set up as shown on Figure 1.
  2. Firstly, the string was attached to the front of the cart and the other end of the string looped and suspended over the pulley.
  3. A long piece of ticker-tape was attached to the back end of the cart and pulled through the ticker-tape timer.
  4. The 200g or 0.200 kg weight was hooked on to the loop of the string, which was the falling end of the string.
  5. The 500g or 0.500 ...
