What a Drag!
... You have now dealt with conservative forces, forces that conserve the total mechanical energy of a system. The gravitational force and elastic forces are good examples. What about forces like the friction force? They do work but is the work they do stored as potential energy somewhere? If so, where? ...

Physics 107 HOMEWORK ASSIGNMENT #4
... *58 The person in the drawing is standing on crutches. Assume that the force exerted on each crutch by the ground is directed along the crutch, as the force vectors in the drawing indicate. If the coefficient of static friction between a crutch and the ground is 0.90, determine the largest angle the ...

... In pure translation like in sliding, the sole purpose of friction is to oppose relative motion between surfaces. In the case of rolling, friction converts a part of one type of acceleration to another (from linear to angular as in this case). Probably more apropos would be saying that friction chang ...

The Nature of Force
... Friction is the force that one surface exerts on another when the two rub against each other. Friction opposes motion. Friction acts in a direction opposite to the object’s direction of motion. ...

A Net Force
... Fg 1. The net force is simply determined by multiplying the object’s mass by its acceleration. Fnet = ma Fnet = (10kg)(4m/s2) = 40N 2. From the free-body diagram, the net force is the sum of the forces acting in the xdirection. We will then solve the relationship for the frictional force. Fnet = FA ...
