1
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
CASE STUDY: A mass-spring system is used in a car's suspension. The car hits a bump, and the mass-spring system oscillates.
All of the following describe the car's suspension except...
Question 5
CASE STUDY: A scientist is studying the motion of a mass attached to a spring in a laboratory. The mass is displaced and released, causing it to oscillate.
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
CASE STUDY: A spring is fixed at its upper end. A weight is attached to its lower end, causing the spring to stretch.
All of the following are correct applications of Hooke's Law except...
Question 10
CASE STUDY: A spring is compressed and then released, causing it to oscillate. The motion is observed and recorded.
Select three correct descriptions of the motion...
