Simple Harmonic Motion

Question 1

State features of simple harmonic motion

Answer 1

The time period is independent of the amplitude
As the amplitude of the swing decreases the max velocity decreases, time is constant
Constant time period

Question 2

Define period

Answer 2

The time taken for one complete oscilation

Question 3

Define frequency

Answer 3

The number of complete oscillations per unit time

Question 4

Describe the force and acceleration of simple harmonic motion

Answer 4

The oscillation has an equillibrium position and a force is required to displace the object from it
There is a restoring force which is always toward the equillibrium position hence the acceleration is also towards the equillibrium position
The greater the restoring force the greater the acceleration directed towards equilllibrium
The acceleration is directly proportional to the to the distance from the equilibrium position
Acceleration is in the opposite direction to displacement

Question 5

What does isochronus mean

Answer 5

The period is independent of the amplitude

Question 6

What is w^2 in the equation a=-w^2x

Answer 6

Angular frequency
