Kinetic energy
The energy of motion
Potential
Energy that is stored
Example of potential and kinetic energy
A roller coaster, and a ball
Full body diagram
Gravity, normal, friction, applied
Inertia
an object in motion stays at rest unless acted upon another force
Newtons third law
For every force in nature, there is an equal and opposite reaction (Recoil force of a gun)
work
an energy transferred to or from an object via the application of force acting along a displacement
Law of conservation
Energy can't be created or destroyed Vm=Mv
Elastic, Inelastic, Perfectly inelastic
Elastic: n n Inelastic: nn Perfectly inelastic: nn
Velocity in a displacement vs time graph
--->
velocity
speed
acceleration
speed+direction
Wavelength
the messure between crest to crest
amplitude
the measure of half a wave
Frequency
Amount of waves that occur a certain period of time
period
The time required for one completed cycle of vibration at a certain time
compression
The wave particles are close together
rarefaction
The wave particles are far apart
What is the difference between transverse and longitudinal waves
Transverse: The wave is perpendicular to the medium Longitudinal: The wave is parallel to the medium
Constructive interference
The wave passes through each other
Destructive interference
The waves combine destructively
