Overcoming starting friction

 We can infere the starting friction that needs be overcome by using an inclined plane and a bottletop racer. / starting%20friction_Trim.mp4

Collecting data via trigonometry

 Starting friction as a force that opposes a car starting from rest. We can infer this friction by measuring the moment it moves as the angle on an inclined plane is increased, starting at zero. Once we have a series of results for a car we can call this baseline data, ie data we can compare if we change a variable. eg mass of the car. QandD Trig lesson sin (O) = opp/hyp sin (30) = 0.5 type arcsin(opp/hyp) in degrees into your browser  eg arcsin(500/1000) in degrees answer = 30 degrees

Collecting data

 One method of collecting data is to take 5 measurements, ignore the largest and smallest, the average the remaining 3. The best way to present data is in a table.

Changing a variable wheels, axles and mass

 It is common for racing teams in F1 motor sports to arrive with a semi-trailer packed with gear to monitor the cars before, during and after the event. The quest is the same. What is the baseline data, how can it be changes, will it improve performance? These are multi million dollar operations. So they are monitored by lots of people. As there is too much data for one person to monitor at this level, so a team must be able to work together to help there driver win a race. Daniel Ricchiardo is a champion F1 racing car driver from Duncraig in Western Australia. He learned to drive at Marbaghello's Raceway in Wanneroo.  His nickname is the "Honey Badger" and he is a supporter of the West Coast Eagles.
