Laws of Physics
Objects attract one another in direct proportion to their combined mass
Law of Gravity
Charges moving due to a potential difference
Electrical work
Describes the relationship between force and acceleration
F = m*a
When a wave bounces off of something
reflection
Newton's First Law of Motion
An object will remain at rest unless that state is changed by an external force
Compound
Force moving an object through a distance
Mechanical work
Ohm's Law
V = IR
Change in direction of a wave passing from one medium to another
Refraction
Newton's third Law
For every action there is an equal and opposite reaction
Result of combining two or more substances, such that each maintains its chemical identity.
Mixture
Transfer of energy from one molecule to another by direct contact
Conduction
Kinetic Energy
KE = 1/2 mV2
When a wave encounters an obstacle or opening and bends around the corners
Diffraction
The Second Law of Thermodynamics
Heat flows between two objects in contact reach equal entropies
Covalent bond
Movement of heat energy by a fluid such as water or air
Convection
Potential Energy
PE = mgh
Net effect of the combination of two or more wave trains move on intersecting or coincident paths
Interference
All objects that have mass have intrinsic energy even when they are stationary.
Complete transfer of valence electrons between atoms which generates two oppositely charged ions
Transfer of heat by electromagnetic waves
Radiation
Wave equation
v = fλ
increased amplitude that occurs when the frequency of one wave matches another wave
Resonance
