... the weight of the object being lifted. This force is applied to one end of the rope that goes over a fixed pulley. The effort force is exerted on the other end of the rope, in opposition to the resistance force. A movable pulley (see Figure 2) moves along the rope with the resistance force, and the ...

When two surfaces or particles approach closer than a few
... In considering the forces between two molecules or particles in liquids, i.e. solvents, several effects are involved that do not arise when the interaction occurs in free space. This is because an interaction in a medium always involves many solvent molecules, i.e. it is essentially a many-body prob ...

... When an object is moved from a position of stable equilibrium, it experiences a restorative force. A restorative force tends to make it return to equilibrium. In some instances the size of this restorative force is directly proportional to the object’s displacement from equilibrium. The resulting mo ...

Chapter 8 Rigid Body Rotation: Axis Direction Fixed - RIT
... only rotations about an axis of rotation that has a fixed orientation so that the rigid body rotates in a fixed plane. We will define again the things you saw in University Physics, center of mass, moment of inertia, Newton’s second law for rotation, angular momentum for this situation. We will exte ...

... To find an equation for uniform fields, we will once again draw a parallel with gravitational potential energy. Consider a mass sitting in a uniform gravitational field at some height. The mass will tend to move from… As it does it… If we allow the mass to fall the work done on it (W = ) is negative ...
