masses oscillating vertically on a spring in air.
pendulum oscillating in treacle
Suspension system on a vehicle
friction of a swing
2
Displacing a mass on a spring and allowing it to oscillate is.....
A free oscillation
A forced oscillation
3
What is not an example of simple harmonic motion
Masses attached to a spring bouncing up and down
Ball bouncing on the floor, bounces back to initial height
swing
ruler clamped over edge of bench and hit
4
An object is displaced from equilibrium and released, where is it's velocity greatest?
Position of Maximum Displacement
It's unknown
Position of Equilibrium
The Position depends upon mass of object

negative sine graph
cosine graph
linear
parabolic graph
9

Driving frequency ⦥ natural frequency
Driving frequency ⦤ natural frequency
Driving frequency=natural frequency
Driving frequency = 2x natural frequency
10
