Topic 7:Oscillations

Question 1

Define simple harmonic motion

Answer 1

Acceleration is proportional to the displacement in the opposite direction towards the equilibrium.

Question 3

Give the two equations you could use to find the Acceleration of an oscillation

Answer 3

A=-ω^2x
W=2πf

Question 4

How would you change displacement graph for an oscillation into a velocity graph

Answer 4

Move forward by one quarter

Question 5

How would you change Velocity graph for an oscillation into a Displacement graph

Answer 5

Move backwards by one quarter

Question 6

How would you change displacement graph for an oscillation into a acceleration graph

Answer 6

Flip it

Question 7

True or false?

you can convert directly from a velocity graph into an acceleration graph

Answer 7

False

you must convert it to displacement then acceleration

Question 8

What type of graph is a SHM graph

Answer 8

Sinusoidal

Question 9
