Formulae Flashcards
Give the equation for power in terms of current and resistance.
Power = current^2 × resistance
Give the equation for power in terms of current and potential difference.
Power = current × potential difference
Give the equation for energy transferred in terms of potential difference and charge
Energy transferred = potential difference × charge
Give the equation for charge in terms of time and current.
Charge = current x time
Give the equation for resistance in terms of potential difference and current.
Resistance = Potential difference ÷ current
Give the equation for current in terms of charge and time.
Current = charge ÷ time
Give the formula for kinetic energy.
kinetic energy = 0.5 × mass × velocity^2
Give the formula for velocity.
Velocity = displacement ÷ time
Give the formula for acceleration.
Acceleration = change in velocity ÷ time
Give the formula for specific heat capacity.
SHC = change in thermal energy ÷ (mass × change in temperature)
final velocity^2 × initial velocity^2 = ___________________
final velocity^2 × initial velocity^2 = 2 × acceleration × distance
Give the equation for Newton’s Second Law.
Force = mass × acceleration
Give the formula for power in terms of work done and time.
Power = work done ÷ time
Give the formula for power in terms of energy and time.
Power = energy ÷ time
Describe the relationship between power and energy.
Power is directly proportional to energy. The more energy transferred, the greater the power will be.
