a = acceleration (m/s2)
F = force (N = kg m/s2)
KE = kinetic energy (J = kg m2/s2)
m = mass (kg)
p = momentum (kg m/s)
s = position (m)
t = time (s)
v = velocity (m/s)
v0 = velocity at time t=0
W = work (J = kg m2/s2)
x(t) = position at time t
x0 = position at time t=0
v = δs/δt = ds/dt
a = δv/δt = dv/dt = d2s/dt2
Centripetal Acceleration
ac = v2 / R
p = mv
Angular Momentum
L = mvr
Vector form L = pxR
R is the radius vector
F = dp/dt = d(mv)/dt
F = ma (Constant Mass)
I = FΔt
Energy
Kinetic Energy
KE = 1/2 mv2
Potential Energy
PE = mgh (near the earth's surface)
g is the acceleration due to gravity, one the physical constants.
Useful derived equations
Position of an accelerating body
x(t) = 1/2at2 + v0t + x0
Equation for velocity
v2=v02 + 2aΔx
where Δx is the change is position.
Someone please add the equations for gravitational, electric, and magnetic forces
