If the mass of M1 is doubled while the force remains constant, the acceleration of M1 will be halved according to F = ma, since a = F/M1. If the mass of M2 is doubled, this increases the force exerted on M1 due to gravity, thus increasing acceleration as long as M1's mass remains unchanged. When both M1 and M2 are doubled simultaneously, the impact on acceleration depends on the net effect of the forces; however, since both masses are increased proportionally, the acceleration may remain the same if the system is balanced. In summary, M1's acceleration decreases with its own mass increase, increases with M2's mass increase, and could remain the same if both masses are increased proportionally.
This experiment is testing the relationship between mass and acceleration. A string is connecting the car (M1) to a mass (M2). Use the equation for Force F=ma to discuss; What will happen to the acceleration of the car (M1) if the mass of M1 is doubled? What will happen to the acceleration of the car (M1) if the mass of M2 is doubled? What will happen to the acceleration of the car (M1) if the mass of M1 AND M2 are both doubled? only answer in four sentences
