Title: Simple Harmonic Motion

1
Simple Harmonic Motion
• Oscillatory Motion

2
Definition
Repetitive back-and-forth movement through a
central, or equilibrium, position in which the
maximum displacement on one side is equal to the
maximum displacement on the other.

Motion that repeats in a simple pattern Mr. Dole

Period and Frequency
Period Time needed to complete one
cycle Frequency Number of cycles per second
4
Equation
Mass and Spring
Pendulum

Problem 1
What is the period of a mass and spring system
that consists of a 2 kg mass on a spring with a
spring constant of 100 N/m?
6
Problem 2
What is the period of a mass and spring system
that consists of a 4 kg mass on a spring with a
spring constant of 100 N/m?
7
Problem 3
What is the period of a 5 m long pendulum on the
earth?
8
Problem 4
What is the period of a 5 m long pendulum on the
moon (g1.6 m/s2)?
9
Problem 5
A 5 kg mass is placed on a spring and set into
motion. The period of the motion is 0.63 s. What
is the spring constant of the spring?

Problem 6
The frequency of a pendulum is measured to be
0.25 Hz. What is the length of the pendulum?
