Which of the following is an example of periodic motion?

• a car traveling down a winding road.

• A carpenter hammering a nail

• the back-and-forth movement of a swing

• A wrecking ball hitting a brick building.

When is the potential energy of a spring system in motion at its maximum?

• when the spring is compressing with a given velocity.

• when a spring is stretched to its greatest displacement.

• when the spring reaches its equilibrium position.

• when the mass reaches its maximum velocity.

The maximum displacement of a spring from its equilibrium position is called its

• amplitude

• cycle

• period

• rest position

Why does a spring system eventually come to a stop?

• Energy is lost to friction in the system.

• The mass resists motion

• The restoring force becomes unable to return the spring to equilibrium

• the spring is itself stiff.

a damped oscillator

• assists the input force to maintain the amplitude of the oscillations.

• causes objects to vibrate at greater and greater amplitudes.

• overcomes the natural losses of energy

• intentionally decreases the amplitude of the oscillations.
