Physics M13 Vibrations and Waves Notes Review

________________________ motion is the movement of an object back and forth between two opposing points.

• Periodic

• Linear

• Random

• Static

In each example, the object has one position at which the net force on it is zero. At that position, the object is in __________________________.

• Equilibrium

• Oscillation

• Inertia

• Static

Whenever the object is pulled away from its equilibrium position, the net force on the system becomes __________________________ and pulls the object back toward equilibrium.

• Restorative

• Disruptive

• Repulsive

• Neutral

Any system in which the force acting to __________________________ an object to its equilibrium position is directly proportional to the displacement of the object shows simple __________________________ motion.

• Restore, Harmonic

• Push, Harmonic

• Restore, Oscillatory

• Pull, Rhythmic

The period (T) is the time needed for an object to repeat __________________________ complete cycle of the motion.

• One

• Two

• Half

• Multiple

The amplitude of the motion is the __________________________ distance the object moves from the equilibrium position.

• Maximum

• Minimum

• Average

• Total

When a force is applied to stretch a spring, such as by hanging an object on its end, there is a direct __________ relationship between the exerted force and the displacement.

• proportional

• exponential

• inverse

• logarithmic

The slope of the graph is equal to the spring constant, given in units of __________.

• N/m

• lb/in

• kg/s

The area under the curve represents work done to stretch the spring. It therefore equals the __________ potential energy stored in the spring as a result of that work.

• elastic

• kinetic

• gravitational

• thermal

Hooke’s Law Equation: F = kx, where k is the spring constant, which depends on the __________ and other properties of the spring.

• material

• length

• temperature

• age
