Chapter 17 - Oscillations

Question 1

What is the difference between displacement and amplitude

Answer 1

Displacement is the distance from the equilibrium position.

Amplitude is the max displacement

Question 2

What is a Period?

Answer 2

Period, T, is the time taken to complete one full oscillation

Question 3

What is frequency?

Answer 3

the number of oscillations per unit time

Question 4

What is Phase difference?

Answer 4

ϕ – the fraction of an oscillation between the position of two
oscillating objects

Question 5

What is angular frequency ?

Answer 5

ω – the rate of change of angular position

Question 6

What is simple harmonic motion?

Answer 6

Simple harmonic motion is a type of oscillation, where the acceleration of the oscillator is
directly proportional to the displacement from the equilibrium position, and acts towards the
equilibrium position
The equation for SHM is 𝑎 = − 𝜔^2 x
