A New Principle of Conservation of Energy
... In a system of N particles, the total work W done by the forces acting on the system of particles is equal to the change in the total kinetic energy K of the system of particles. W = +∆ K In a system of N particles, the total work W done by the conservative forces acting on the system of particles i ...

Newton`s Laws of Motion
... Forces exist in pairs….. “simultaneous” and “mutual” in effect, “equal” in magnitude, “opposite” in direction. The third law brings together the first and second laws, which deal with single bodies. The third law makes clear that “forces” are actually interactions between bodies. Force is not what o ...

... In General Relativity, we’ve told you that particles move along worldlines that are geodesics of the ³ spacetime they inhabit (that is to say, their path is an extremum of ds). It’s not intuative to see how more familiar Newtonian mechanics solutions come out of the weak field limit for GR, so let’s ...

10-9 Newton`s Laws for Rotation
... In Chapter 3 we considered Newton’s three laws of motion. The first two of these laws have analogous statements for rotational motion. Newton’s First Law for Rotation: an object at rest tends to remain at rest, and an object that is spinning tends to spin with a constant angular velocity, unless it ...

Uniform circular motion
... If the force acting on an object is always at right angles to its velocity (momentum), then the object moves with constant speed in a circle. Describe the force that keeps the Moon in orbit round the Earth as a centripetal force if you want, but remember it’s GRAVITY. ...
