Center of Mass, Angular Momentum
... It always bothered me that if the same impulsive force were applied on the bar between the two masses, i.e. at the CM, the barbell would move at the SAME speed we just calculated for the CM, but without rotation. From energy considerations, it seems that applying the same force in two locations impa ...

determination of the acceleration of an elevator.
... DETERMINATION OF THE ACCELERATION OF AN ELEVATOR. INTRODUCTION: In order for an object to accelerate, there must be a net force acting on it. We know that the direction of the acceleration will be in the same direction as the direction of the net force. The equation for Newton’s 2nd law is F = ma o ...

Coefficient of Sliding Friction
... perpendicular force is the coefficient of kinetic friction between the block and the plane. The coefficient of sliding friction may also be defined as the ratio of the force required to slide an object at uniform speed over a surface to the weight of the object itself. This can be found by weighing ...
