Force (F)
Force = Mass x Acceleration
Acceleration (A)
Acceleration = Change in Speed / Time
Speed (S)
Speed = Distance / Time
Power (P)
Power = Energy / Time
Weight (W)
Weight = Mass x Gravity
Work Done
Work Done = Force x Distance
Gravitational Potential Energy
Gravitational Potential Energy = Mass x Gravity x Height
Kinetic Energy
Kinetic Energy = 1/2 mass x Velocity* Squared
Density
Density = Mass / Volume
Force (Spring)
Force (Spring) = Spring Constant x Extension
Moment
Moment = Force x Perpendicular Distance
Momentum
Momentum = Mass x Velocity
Momentum Before
Momentum Before = Momentum After
Efficiency
Efficiency = Useful Energy / Total Energy x 100 (%)
Pressure
Pressure = Force / Area
Pressure 1 x Volume 1
Pressure 1 x Volume 1 = Pressure 2 x Volume 2
Wave Speed
Wave Speed = Frequency x Wavelength
Magnification
Magnification = Height of Image / Height Of Object
Refractive Index
Refractive Index = Sin i / Sin r
The Frequency controls what and is what?
The frequency controls pitch and is the number of waves per second
The amplitude is what and controls what?
The amplitude is the height of a wave and controls the volume
The quality is what and controls what?
The quality is the shape of the waves and controls the timbre
Voltage
Voltage = Current* Squared x Resistance (V=I2R)
Power
Power = Voltage x Current (P=VI)
