## Equations

 Resultant Force equals Mass*Acceleration Kinetic Energy equals Gravitational Potential Energy equals Mass*9.81*Height Ohm's Law: Voltage equals Current*Resistance The reciprocal of thetotal resistance in a parallel circuit is equal to the sum of thereciprocals of the resistances The total resistance in a series circuit is equal to the sum ofthe resistances The electric power delivered to a component equalscurrent*voltage*time % Final velocity equals initial velocity+acceleration*time Energy equals Power*Time Weight equals Mass*9.81 Energy equals Mass*Specific Heat Capacity*Rise in Temperature Wave speed equals Frequency*Wavelength Density equals Mass divided by Volume Refractive Index equals sin of angle of incidence divided bysin of angle of refraction Criitical angle Hooke's Law: Force equals Force Constant*Extension Pressure equals Force divided by Area Work Done equals Force*Distance Boyle's Law: Pressure*Volume=constant if the temperature iskept constant Pressure Law: Pressure divided by Temperature is constant ifthe Volume is kept constant Charle's Law: Volume divided by Temperature is constant if thePressure is kept constant
