Newton's 2nd law and acceleration It relates the net force to the acceleration net一 ∑码 ma A force is what changes the velocity of a particle No net force: no change in velocity The constant of proportionality is the mass For a given Fnet a more massive object will undergo a smaller acceleration (and vice versa) Physics 121: Lecture 4, Pg 10Physics 121: Lecture 4, Pg 10 Newton’s 2nd law and acceleration It relates the net force to the acceleration A force is what changes the velocity of a particle No net force: no change in velocity The constant of proportionality is the mass For a given Fnet a more massive object will undergo a smaller acceleration (and vice versa)
