Essential Formulas Flashcards
Acceleration formula
acceleration = change in velocity / time taken
Force formula
Force = mass x acceleration
Weight formula
Weight = mass x gravitational field strength
Momentum formula
momentum = mass x velocity
change in gravitational potential energy
Change in gravitational potential energy = mass x gravitational field strength x change in vertical height
kinetic energy formula
Kinetic energy = 1/2 x mass x (speed)^2
efficient formula
efficiency = useful energy transferred/ total energy transferred
wave speed formula
wave speed = frequency x wavelength
wave speed
wave speed = distance / time
work done formula
work done = force x distance moved in the direction of force
energy transferred formula
energy transferred = charge x potential difference
charge formula
charge = current x time
potential difference formula
potential difference = current x resistance
power formula
power = energy transferred / time taken
electrical power formula
electrical power = current x potential difference
