Equations Physics CS (Higher) Flashcards
How do you calculate force?
Force = change in momentum ÷ time
How do you calculate energy transferred?
Energy transferred = current x potential difference x time
How do you calculate change in thermal energy?
Change in thermal energy = mass x specific heat capacity x change in temperature
How do you calculate thermal energy needed for a change in state?
Thermal energy needed for a change in state = mass x specific latent heat
How do you calculate energy transferred in stretching?
Energy transferred in starching = 1/2 x spring constant x (extension)²
How do you calculate work done?
Work done = force x distance moved in the direction of the force
How do you calculate power?
Power= work done ÷ time taken
How do you calculate energy transferred from charge moved?
Energy transferred= charge moved x potential difference
How do you calculate charge?
Charge = current x time
How do you calculate power from energy transferred?
Power = energy transferred ÷ time taken
How do you calculate electrical power?
Electrical power=current x potential difference
How do you calculate electrical power from resistance?
Electrical power= (current)² x resistance
How do you calculate density?
Density = mass ÷ volume
How do you calculate force extracted on a spring?
Force extracted on a spring = spring constant x extension
How do you calculate distance travelled?
Distance= speed x time
