What is the net force acting on a yo-yo when it doesn't move?

Answer 1

The net force acting on the yo-yo when it doesn't move is 0 N.

We know this because, according to Newton's first law of motion, an object at rest will remain at rest and an object in motion will continue to move at a constant speed unless acted upon by an unbalanced force; in these situations, there is no acceleration—that is, zero acceleration.

We get the formula Force = mass x acceleration #(F = ma)# from Newton's second law of motion. Since the yo-yo is at rest, its acceleration is 0, and the net force acting on it is 0. #F = m xx 0 = 0 "N"#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
