Physical Formulae

Constant Velocity Equation
v=st s is the displacement (or distance);
v is the velocity (or speed);
t is the time taken.

Constant Acceleration Equations
v=u+at s=vt- 1 2 a t2

s=ut+ 1 2 a t2 s= u+v 2 t v2 = u2 +2as

See also SUVAT table

s is the displacement;
u is the initial velocity;
v is the final velocity;
a is the acceleration;
t is the time taken.

Circular Motion
ω=|dθdt|=2πT v=2πrT=ωr a=ωv=ω2r=v2r ω=2πf=2πT ω is the angular speed (or angular frequency) in radians per second;
θ is the angle moved through in radians;
T is the time period in seconds. v is the speed in metres per second;
r is the radius of the circular path;
a is the centripetal acceleration;
f is the frequency in hertz;

Simple Harmonic Motion
x(t)=Asin(ωt+φ) a = d2x(t) dt2 = - ω 2 x (t) x is the displacement from equilibrium in metres;
t is the time from start in seconds;
A is the amplitude of the oscillation in metres;
ω is the angular frequency in radians per second;
φ is the phase difference in radians.

Newton's Second Law
F =ma =dpdt F is the force on the object being accelerated in newtons;
