Three forces comprise the net force, her weight, and the tension forces from the left and right sides of the rope. We will resolve the forces into components and set the sum of th ...

If gravity is the only force acting on an object, then we find the object will accelerate at a rate of 9.8m/s2 down toward the center of the Earth. Gravity acts on all bodies in the universe, and each bodies' gravitational effects are related. The bo ...

... Newton’s laws still apply to every mass element of the extended body, so there is motion, momentum, work, energy (potential and kinetic), etc. associated to the motions about the center of mass of the body. For a rigid body, that motion takes the form of rotations. Relaxing the rigidity assumption, ...
