Understanding Periodic and Simple Harmonic Motion

Concepts covered:periodic motion, simple harmonic motion, restoring force, equilibrium position, oscillation amplitude

This chapter focuses on the study of periodic motion, which is defined as motion that repeats in a regular cycle over equal time intervals. It explains simple harmonic motion, a special case of periodic motion, characterized by a restoring force proportional to the displacement from the equilibrium position.

Question 1

A restoring force is proportional to displacement in simple harmonic motion.

Question 2

Why isn't Earth's orbit simple harmonic motion?

Question 3

What happens when a mass is pulled from equilibrium?

Question 4

All of the following describe the car's suspension except...

Question 5

Select three correct descriptions of the motion.

2

Understanding Hooke's Law and Elastic Potential Energy

Concepts covered:Hooke's Law, spring constant, elastic potential energy, force-elongation relationship, graphical analysis

Hooke's Law describes the relationship between the force applied to a spring and the resulting elongation. The chapter explains how to graph this relationship, calculate the spring constant, and determine the elastic potential energy stored in the spring.

Question 6

A mass on a spring exhibits simple harmonic motion when displaced.

Question 7

What type of motion does a mass-spring system exhibit?

Question 8

How do you calculate the elastic potential energy in a spring?

Question 9

All of the following are correct applications of Hooke's Law except...

Question 10

Select three correct descriptions of the motion...
