Document Summary

This is a small table with moment of inertia of some of the most used objects. First law: every object persists in its state of rest or uniform motion unless is compelled to change that state by forces impressed upon it. ~v = 0 or ~v = 0 if f~ = 0. Law: to every action there is always opposite and equal reaction. = m~g where g is the gravitational acceleration = 9. 8m/s2 third. Torque : ~ = ~r f = ~rftangent. Right hand rule (rhr) is used to find the direction of ~ , l, ~~ P~ = 0when f~ = 0 and l~ = 0when ~ = 0 also from newton"s second law : For every object we first draw a force digram to recognize all the forces acting on the object. A simple example would be the block standing on top of the table.
