Unit 7 - Simple Harmonic Motion
3/6/19
Learning Target One :
Restoring Force - A force that pushes towards equilibrium.
Period - The time it takes to complete one full cycle.
Frequency - How many cycles are completed per second.
Amplitude - The maximum displacement from equilibrium.
Angular Frequency - The same as angular velocity.
Learning Target Two :
Energy Transfers - In a oscillating system energy transfers between kinetic on the x axis and potential energy at the height of the wave.

Learning Target Three :
Spring Period Dependence - Ts = square root of m over k
Pendulum Period Dependence - Tp = square root of l over g
Learning Target Four :
Inertial Mass - a mass parameter giving the inertial resistance to acceleration of the body when responding to all types of force.
Gravitational Mass - mass determined by the strength of the gravitational force experienced by the body when in the gravitational field g.
Learning Target Five :
In order to determine if a oscillator is simple harmonic motion it has to be one of the two below
Learning Target Six :
Learning Target Three :
Spring Period Dependence - Ts = square root of m over k
- m = mass
- k = spring constant
Pendulum Period Dependence - Tp = square root of l over g
- l = the length
- g = gravitational field strength
Learning Target Four :
Inertial Mass - a mass parameter giving the inertial resistance to acceleration of the body when responding to all types of force.
- to find inertial mass you would need to repeat a similar spring trial, measure the period and amplitude then you can calculate it
Gravitational Mass - mass determined by the strength of the gravitational force experienced by the body when in the gravitational field g.
- to find gravitational mass you would need to measure the amount on a appropriate scale
Learning Target Five :
In order to determine if a oscillator is simple harmonic motion it has to be one of the two below
- restoring force is proportional to displacment
- object follows sin or cosine position time relationship
