Equations 5th Form Flashcards
Speed, distance, time
Speed = distance/time
Acceleration, change in velocity, time taken
Acceleration = change in velocity/time taken
Force, mass, acceleration
Force = mass x acceleration
Weight, mass, gravitational field strength
Weight = mass x gravitational field strength
Power, current, voltage
Power = current x voltage
Energy transferred, current, voltage, power
Energy transferred = current x voltage x power
Voltage, current, resistance
Voltage = current x resistance
Charge, current, time
Charge = current x time
Energy transferred, charge, voltage
Energy transferred = charge x voltage
Wave speed, frequency, wavelength
Wave speed = frequency x wavelength
Frequency, time period
Frequency = 1/time period
Refractive index, angle of incidence and refraction
N = sin(i)/sin(r)
Critical angle, refractive index
Sin (c) = 1/n
Relationship between input (primary) and output (secondary) voltages, and the number of turns in a transformer
Input (primary) voltage/ output (secondary) voltage = primary turns/secondary turns
Input power, output power in a transformer
Input power = output power (100% power)
Power, current, voltage
Power = current x voltage
Energy transferred, current, voltage, time
Energy transferred = current x voltage x time
Voltage, current, resistance
Voltage = current x resistance
Charge, current, time
Charge = current x time
Energy transferred, charge, voltage
Energy transferred = charge x voltage
