Planning In this investigation I will investigate the relationship between force, mass and acceleration. Force is proportional to acceleration because if I push a trolley harder the acceleration is higher. If I put something in the trolley then the acceleration would lower so the mass is inversely proportional to the acceleration. Force ? Acceleration Force ? Mass-1 The formula could be rewritten as: Force = Mass x Acceleration (N) = (Kg) x (m/s2) This investigation will attempt to prove this formula in a practical. To calculate the force I will use gravity acting on weights as shown in my diagram below. 100 g will give a force of 0.98 N. Mass can be measured on a scale. Acceleration will be measured using a light gate as shown below. The formula for acceleration is: Acceleration = Change in speed / time (m/s2) = (m/s2) / (s) The formula for speed is: Average speed = Distance / time (m/s) =...
