1. The problem statement, all variables and given/known data Hello! I was thinking about designing an experiment in which i would investigate the angle of incline of a surface and the acceleration of a toy car moving down it. I will most likely be using a stopwatch. My question is: How should i go about calculating the acceleration without having to account for air ressistance and friction etc - or do i have t do that? I wanna keep it relatively simple. 2. Relevant equations F=ma delta V/ delta t = acceleration Suvat equations? 3. The attempt at a solution I was thinking about simply taking the time and the displacement (42cm)and using this. Possibly suvat equations but i really don't know? Thanks!
