Oscillations Quiz

What is an example of a free oscillation?

• A swinging pendulum

• A car driving on a highway

• A person walking

• A stationary object

What causes a free oscillation to eventually stop?

• Gravity

• Friction

• Electric current

• Magnetic field

What is a forced oscillation?

• An oscillation that occurs naturally

• An oscillation that is caused by an external force

• An oscillation that never stops

• An oscillation that occurs at a random frequency

What is the difference between a free oscillation and a forced oscillation?

• Free oscillations are caused by external forces, while forced oscillations occur naturally.

• Free oscillations have a constant amplitude, while forced oscillations have a decreasing amplitude.

• Free oscillations are caused by internal forces, while forced oscillations are caused by external forces.

• There is no difference between free and forced oscillations.
