Newton's second law states that the force produced by a moving object depends on its mass and acceleration. which is an example of this? two boulders move at the same rate of acceleration; the boulder with the smaller mass produces a greater force. two boulders move at the same rate of acceleration; the boulder with the greater mass produces a greater force. a runner accelerates at a rate of 1 meter per second per second during a race.
