All U1 Equations Flashcards
what is the equation for Density
Density = mass / volume
D = m/V
what is the equation for velocity
Velocity = displacement / time
V = S / t
what is the equation for work done
Work done = force x distance moved
Wd = F x d
what is the equation for acceleration
Acceleration = (final velocity - initial velocity) / time
a = (v - u) / t
what is the equation for force
Force = mass x acceleration
F = m x a
what is the equation for pressure
Pressure = force / area
P = F / A
what is the equation for momentum
Momentum = mass x velocity
p = m x v
what is the equation for power
Power = work done / time taken
P = Wd / t
what is the equation for charge
Charge = current x time
Q = I x t
what is the equation for Voltage
Voltage = energy / charge
V = E / Q
what is the equation for Resistance
Resistance = Voltage / current
R = V / I
what is the equation for Sin( °)
Sin( °) = Opposite / Hypotenuse
what is the equation for Cos( °)
Cos( °) = adjacent / hypotenuse
what is the equation for Tan( °)
Tan( °) = opposite / adjacent
what is the equation for moment
moment = force x perpendicular distance from the pivot
M = F x d
What is the equation for Speed
Speed = distance / time
S = d / t
What are the SUVAT equations
V = u + at
S = 1/2 x (u+v) x t
S = ut + 1/2at^2
V^2 = u^2 + 2as
what is the equation for impulse
Impulse = force x time
/\p = F x t
what is the equation for change in momentum
Change in momentum = force x time

Gravitational potential energy =
mass x gravity x hight
PEg = m x g x h
what is the equation for kinetic energy
Kinetic energy =
1/2 x mass x velocity^2
KE = 1/2 x m x v^2
