Section 1

(27 cards)

Would conducting a vertical mass- spring experiment in different gravity affect the displacement of the system?

Front

YES. The weight would change which would change the maximum displacement and energy of the system.

Back

Would conducting a mass- spring experiment in different gravity affect the period of the system?

Front

NO. Gravity does not affect the period.

Back

Minus sign indicates

Front

that the force is in the opposite direction of the displacement

Back

Amplitude

Front

Maximum displacement from equilibrium Symbol: A Units: m

Back

Restoring force is

Front

a force that restores a system back to its equilibrium position

Back

In Simple Harmonic Motion, when is Potential Energy at its maximum value?

Front

PE is max when the object is at the greatest displacement from the equilibrium (amplitude) Pendulum: mgh Spring: 1/2 kx^2

Back

Period of a Spring Mass system

Front

Back

Frequency

Front

Number of cycles per second Symbol: f Units: Hertz (Hz)

Back

Would conducting a pendulum experiment in different gravity affect the restoring force on the pendulum?

Front

YES. The restoring force is proportional to gravity.

Back

In Simple Harmonic Motion, when is velocity at its maximum value?

Front

Velocity is at its maximum as the object passes through the equilibrium point. When KE is max

Back

If the frequency of a sound wave is doubled then the wavelength

Front

Halves, because the two are inverses.

Back

Equilibrium is

Front

the position or state that the system naturally wants to return to

Back

What is a restoring force?

Front

A force that gives rise to an equilibrium in a physical system. If the system is disturbed from equilibrium, then the restoring force will tend to bring the system back toward equilibrium.

Back

Simple Harmonic Motion is

Front

a special type of vibration

Back

Simple Harmonic Motion is defined as

Front

1. Back and forth motion (a cycle) of an object over the same path 2. Each cycle taking the same amount of time (period) 3. the restoring force is proportional to displacement

Back

What is the equilibrium of displacement position of a system involving a spring?

Front

The place where the spring does not move and is unstretched or uncompressed.

Back

x is the

Front

displacement from the equilibrium position in m

Back

Criteria for a Simple Pendulum

Front

Mass is concentrated in the bob String/Rod is considered to have no mass Initial displacement is less than ~15 degrees

Back

What is the restoring force on a pendulum?

Front

Back

Period of a Simple Pendulum

Front

Back

Hooke's Law

Front

F = -kx

Back

Would conducting a pendulum experiment in different gravity affect the period of the system?

Front

YES. The period is inversely proportional to the square root of the period.

Back

In Simple Harmonic Motion, when is Kinetic Energy at it's maximum value?

Front

KE is max when the speed is max - the object is passing through the equilibrium position

Back

Period

Front

Time necessary for one complete cycle Symbol: T Units: s

Back

Period and Frequency are

Front

inverses of each other f = 1/T T = 1/f

Back

What is the total energy of a spring oscillating equal to?

Front

Back

k is the

Front

spring constant measured in N/m

Back
