RP- Effect of changing force/mass on acceleration of object

• Sample Method:

  1.Set up equipment as shown

  2.Release the trolley and use a stopwatch to take measurements needed to calculate acceleration

  3.Move 100g onto the mass holder

  4.Repeat steps 2 and 3 until all the masses have been placed onto the mass holder

  
• Considerations, Mistakes and Errors:

  -When changing the force it is important to keep the mass of the system constant

  -Fast events can result in timing errors, repeat for accuracy

  -Friction can cause the events to be inaccurate
• Variables:

  Independent:Force or the mass

  Dependent: The acceleration

  Control: Force is mass is changed or mass if force is changed
• Hazards and Risks:

  Can drop masses on feet
