Motion

Equations of Motion (1)

Velocity-time relation

v=u+atv = u + at

Where: v = final velocity, u = initial velocity, a = acceleration, t = time.

Motion

Equations of Motion (2)

Position-time relation

s=ut+12at2s = ut + \frac{1}{2}at^2

Where: s = displacement, u = initial velocity, a = acceleration, t = time.

Force

Newton's Second Law

Force and acceleration

F=maF = ma

Where: F = net force, m = mass, a = acceleration.

Gravitation

Universal Law of Gravitation

Force between two masses

F=Gm1m2r2F = G\frac{m_1m_2}{r^2}

Where: F = gravitational force, G = gravitational constant, m₁, m₂ = masses, r = distance between centers.
