Formula for Speed
Speed = Distance / Time
Formula for Acceleration
Acceleration = (Final Speed - Initial Speed) / Time
Formula for Final Speed (v2)
Final Speed = Initial Speed + 2 x acceleration x distance
Formula for Density
Density = Mass / Volume
Formula for Pressure
Pressure = Force / Area
Boyle's Law
P1V1 = P2V2 (Pressure and volume of a gas at constant temperature are inversely related)
Formula for Force
Force = Mass * Acceleration
Formula for Gravitational Potential Energy (GPE)
GPE = Mass * Gravitational Field Strength * Height (GPE = mgh)
Formula for Kinetic Energy (KE)
KE = 0.5 * Mass * (Speed^2)
Formula for Power
Power = Work / Time
Formula for Weight
Weight = Mass * Gravitational Field Strength
Formula for Mass
Mass = Weight / Gravitational Field Strength
Formula for Efficiency
Efficiency = (Useful Output Energy / Total Input Energy) * 100%
Formula for Energy
Energy = Power * Time
Formula for Voltage
Voltage = Current * Resistance
Formula for Current
Current = Charge / Time
Formula for Charge
Charge = Current * Time
Formula for Resistance
Resistance = Voltage / Current
