... This is because static friction can vary, precisely counteracting weaker forces that attemp t to move an object. For example, suppose an object feels a normal force of FN = 100 Nand the coefficient of static friction between it and the surface it's on is 0.5. Then, the maximum force that static fric ...

4 Newton`s Second Law of Motion
... • A heavy truck is harder to stop than a small car moving at the same speed. We say that the truck has more momentum than the car. • A small bullet moving at a high speed can have the same large momentum as a huge ship moving at a small speed. By Momentum we mean inertia in motion Momentum = mass ...

... The maximum static friction force is related to the normal force in a similar way as the kinetic friction force. The static friction force acts in response to a force trying to cause a stationary object to start moving. If there is no such force acting on an object, the static friction force is zero ...

Using F = ma
... The law that allows us to be quantitative is the second law. Given a force, we can apply F = ma to find the acceleration. And knowing the acceleration, we can determine the behavior of a given object (that is, where it is and what its velocity is), provided that we are given the initial position and ...
