Laws of Motion
How is force measured?
Newtons
Types of Potential Energy
Gravitational, Elastic, and Chemical
Example of a Conductor
copper or steel
What is a magnet?
a magnetic material with the magnetic poles of the atom are permanently lined up
What is amplitude
distance from rest to crest or trough
Newton's First Law
an object at rest stays at rest, an object in motion stays in motion unless an unbalanced force acts upon it
What is Kinetic energy
energy due to motion
What charges Attract
positive and negitive
What do electromagnets require
conductor, battery, and a magnetic material
What is wavelength
distance from crest to crest or trough to trough
Newtons 3rd Law
For every action there is an equal and opposite reaction
How is energy measured
Joules
What charged repel
like chrges
Electric Motors
electrical to mechanical
What is frequency
number of waves per second
Compare/Contrast mass and weight
Weight changes due to gravity, but mass doesn't change
Friction causes what energy transformation
Thermal energy
Example of an Insulator
Glass or rubber
Electric Genorator
mechanical to electrical
How to calculate frequency
Hertz (Hz)
Friction vs Inertia
Friction is a contact force and inertia is a noncontact
Law of Conservation of Energy
energy can not be created or destroyed
Series Circuit vs Parallel Circuit
Series flows in one direction so if there is a break in the circuit, all the loads would go out. Parallel flows in multiple different directions so if one load goes out, all but the one load would stay on
How are electromagnets useful
they can be turned on and off, can be controlled, and the energy can be turned up and down
How are wavelength, frequency, and pitch all related
the shorter the wavelength, the higher the frequency, the higher the pitch and vise versa
