WebMar 1, 2024 · The maximum force of static friction is: f = μmg newtons μ = coeffficient of static friction = 0.75 m = mass of the object = 59 kg g = acceleration due to gravity = 9.8 m/s 2 Plug in the numbers and compute the answer. You will see that f > the 265 newtons you are applying, so the fridge isn't going anywhere. WebSep 12, 2024 · The magnitude of the frictional force has two forms: one for static situations (static friction), the other for situations involving motion (kinetic friction). What follows is an approximate empirical (experimentally determined) model only. These equations for static and kinetic friction are not vector equations.

WebIf you know the coefficient of static friction and the normal force between the object and the surface the product of these two numbers by definition is the maximum force of static friction. So if you calculate the force to be 49N and 50N doesn't move the object then either the value for the coefficient of static friction or the normal force ...
