Document Summary
If net force on a particle is constant, acceleration is also constant and you can use kinematic equations to find variables of a particle under constant acceleration. If force varies in time, acceleration also changes and kinematic equations can"t be used. Simple harmonic motion: periodic motion that occurs when the force that acts on a particle is always directed toward an equilibrium position and is proportional to the position of the particle relative to the equilibrium position. 12. 1 motion of an object attached to a spring: model for shm. Fs is the restoring force: always directed toward equilibrium position; opposite the displacement of the block from equilibrium. When block displaced from equilibrium and released, it is under net force and an acceleration. 12. 2 analysis model: particle in simple harmonic motion since acceleration is the second derivate of position, the acceleration equation can be expressed as: can replace angular velocity: o, a, w, and are constants of motion.
