Driven harmonic motion
... As the mass moves past the equilibrium postion, an increasing Fs acts to slow the mass as it moves to the left, stopping momentarily at x = -A, and then reversing directions. Motion is repeated symetrically between x = A and x = -A; if there are no nonconservative forces present, mechanical ener ...

... The motion of a particle is governed by Newton’s three laws of motion. First Law: A particle originally at rest, or moving in a straight line at constant velocity, will remain in this state if the resultant force acting on the particle is zero. Second Law: If the resultant force on the particle ...
