PPT-Vibrations and Waves Identify the conditions of simple harmonic motion.

Explain how force velocity and acceleration change as an object vibrates with simple harmonic motion Calculate the spring force using Hookes law OBJECTIVES What is periodic motion A repeated motion eg pendulum swinging that is back and forth over the same path.

Topics. : simple harmonic motion, intro to waves.. Typically, harmonic motion decreases in amplitude with time….this realistic model describes damped harmonic motion.. The damping effect is a result of friction and internal resistance of the system to further motion.. Simple Harmonic . Motion (SHM). periodic. motion about an . equilibrium point . where the restoring force is proportional to the distance from equilibrium. For oscillation to be . SHM, . the forces must always be directed to the . Periodic Motion – any repeated motion with regular time intervals.

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.. Vocabulary.
