CHAPTER 5 APPLICATIONS OF NEWTON`S LAWS • Friction ! static
... Since FAB and FBA cancel each other the result depends on the frictional forces FGA and FGB . • If FGA > FGB then A wins! • If FGB > FGA then B wins! If f = µ s N for both people then the person with greater mass should win! Note that if there’s no friction (e.g., on ice) then FGA = FGB = 0 so no on ...

... to the force causing the object to accelerate. An object is in equilibrium when the vector sum of the forces acting on it is equal to zero. The easiest way to do this is to resolve forces into their x and y components. When the sum of all forces in the x direction is zero (Fy=0). Then the vec ...
