Chapter 17-Simple Harmonic Motion

Question 1

Draw the pendulum and write what the acceleration displacement velocity is at each point.

Question 2

Define amplitude, displacement, frequency, time period

Answer 2

Amplitude- the maximum displacement from the equilibrium position.
Displacement- the distance from the equilibrium position.
Period- the time taken to complete one full oscillation.
Frequency- the number of complete oscillations per unit time.

Question 3

What are the formulas for angular frequency and angular velocity?

Answer 3

Angular frequency(w)= 2piFrequency (scalar quantity)
Angular velocity(w)=change in angular rotation/ change in time

Question 4

Derive acceleration
