Equations Flashcards
Power =
Current x voltage
Energy transferred =
Charge x voltage
(Current x time x voltage)
Voltage =
Current x resistance
Charge =
current x time
equation with specific heat capacity
change in thermal energy = mass x specific heat capacity x change in temperature
pressure difference =
height x density x gravitational field strength
pressure =
force / area
density =
mass / volume
gravitational potential energy =
mass x gravity x height
work done =
force x distance
vertical force =
weight = mass x gravity
force =
mass x acceleration
acceleration =
(final velocity - initial velocity) / time
final velocity^2 =
initial velocity^2 + 2(acceleration x displacement)
v^2 = u^2 + 2as
force = (in relation to momentum)
change in momentum / time taken
impulse =
force x change in time
kinetic energy =
1/2mass x velocity^2
equation linking pressure and volume
initial pressure x initial volume = final pressure x final volume
wave speed =
frequency x wavelength
refractive index =
sin(i) / sin(r)
sin(critical angle) =
1 / refractive index
efficiency =
useful energy output / total energy input
work done =
force x distance moved
gravitational potential energy =
mass x gravity x height
equation linking energy transferred and work done
energy transferred = work done`
Momentum =
mass x velocity
Equation linking force, change in momentum and time
Force = change in momentum / time takeb
