Learn Equations you dumb bitch (21 cards)
Name the equation that links gravitational potential energy, mass, gravitational field strength and height
Gravitational potential energy = mass x gravitational field strength x height
What is the equation for kinetic energy
Kinetic energy = 1/2 x mass x (velocity)2
What is the equation for elastic potential energy
Elastic potential energy = 1/2 x spring constant x (extention) 2
What is the equation that links change in thermal energy, mass, specific heat capacity, temperature change
Change in thermal energy = mass x specific heat capacity x temperature change
What are the three power equation
Power = energy transferred ÷ time
Power = work done ÷ time
Power = potential difference x current
What are the two efficiency equations
Efficiency = useful power output energy transfer ÷ total input energy transfer
Efficiency = useful power output ÷ total power input
What equation links charge flow, current and time
Charge flow = current x time
What equation links potential difference, current and resistance
Potential difference = current x resistance
What equation links energy transfer, power and time
Energy transfer = power x time
What is the equation for energy transferred
Energy transferred = charge flow x potential difference
