3.6.1.2 - Simple Harmonic Motion Flashcards
1
Q
What is SHM?
A
An oscillation in which the acceleration of an object is directly proportional to its displacement from its equilibrium position, and is directed towards the equilibrium.
2
Q
What is the amplitude proportional to?
A
-x (displacement)
3
Q
What does the gradient on a displacement time graph =?
A
Velocity.
4
Q
What does the gradient on a velocity time graph equal?
A
Acceleration
5
Q
What is angular frequency?
A
Frequency of oscillations in rads-1
6
Q
What is phase difference?
A
Difference between two oscillations.
7
Q
How can you calculate phase difference?
A
2π Δ t/T
8
Q
What are antiphase points?
A
Two points which are exactly opposite (π out of phase)
