Mass Moment of Inertia of a Solid Cylinder

 , where:

I = Mass Moment of Inertia of a Solid Cynter about its Main Axis (kg*m^2)

m = Mass of Cylinder (kg)

r = Radius of Cylinder (m)

Mass Moment of Inertia of a Solid Disk (Circle)

The formula for the mass moment of intertia of a uniform solid circular disk (circle) is:

 , where:

I = Mass moment of Inertia of a Uniform Solid Circular Disc (Circle) about its Center Axis

m = Mass (kg)

r = Radius of Circle (m)

Momentum

 , where:

p = Momentum (N*s)

m = Mass (kg)

v = Velocity (m/s)

Natural Frequency of an Oscillating Spring

 , where:

f = Natural Frequency of Oscillating Spring (Hz)

 = 3.1415...

k = Spring Constant (N/m)

m = Mass at end of spring (kg)

Newton's Law of Gravitation

 , where:

F = Gravitational Force (N)

G = Gravitational Constant (m^3/kg/s^2)

m1 = Mass of first object (kg)

m2 = Mass of second object (kg)

r = Distance
