PPT-Simple Harmonic Motion—Spring

Oscillations 2014 Pearson Education Inc If an object vibrates or oscillates back and forth over the same path each cycle taking the same amount of time the motion is called periodic The mass and spring system is a useful model for a periodic system.

Simple Harmonic Motion. This week you move away from rotational motion and begin to study simple harmonic motion. We say that you move away from rotational motion only in the sense that you will not be studying rotating objects as the main focus of the lab. However, it is worth noting that several concepts from rotational motion can be related to simple harmonic motion. You will study three simple harmonic oscillators today: the mass and spring system, the simple pendulum, and the ball and dish oscillator.. deal mainly with . simple harmonic. oscillations where the position of the object is specified by a . sinusoidal. function. .

Physics Classroom has a good lesson on simple harmonic motion under Waves, vibrations.. Oscillations. © 2014 Pearson Education, Inc.. If an object vibrates or oscillates back and forth over the same path, each cycle taking the same amount of time, the motion is called periodic. The mass and spring system is a useful model for a periodic system. The force applied to a spring in order to extend or compress it is proportional to the amount of displacement of the spring from its rest position.. The spring force will be equal and opposite to the applied force, as it is a tension that is a reaction force to the applied force. Explain how force, velocity, and acceleration change as an object vibrates with simple harmonic motion.. Calculate the spring force using Hooke’s law.. OBJECTIVES. What is periodic motion?. A repeated motion (e.g. pendulum swinging) that is back and forth over the same path..
