particle definition & assumption
Mass is concentrated at a single point; ignore air resistance and rotational effects.
Rod definition & assumption
Mass is distributed along a straight line; rigid (no bending).
light definition & assumption
mass is negligible
inextensible definition & assumption
string does not stretch (acceleration is the same for connected objects)
smooth definition & assumption
no friction

Netwons 2nd law for heavier mass
mg-T=ma
Netwons 2nd law for lighter mass
T-Mg=Ma
what is newtons first law
An object stays at rest or constant velocity if the resultant force is zero.
what is newtons 2nd law
F=ma
What is newtons 3rd law
Every action has an equal and opposite reaction
which direction are i and j
i is horizontal, j is vertical
interpolation equation
