Newton’s second law is often described as F = MA but this is misleading and does not describe what happens when multiple forces act. For this reason, a more accurate description is that the sum of all the forces acting on a single object equals mass times acceleration; Or Fnet = MA. Forces which act in the same direction on a single object add together while forces which act in opposite directions subtract. Explain why, if objects in motion stay in motion and objects at rest stay at rest as mentioned in the talk, your bicycle eventually comes to a stop when you stop pedaling. Hint: Which forces are responsible for stopping you?
