Question

Distinguish clearly between like forces and unlike forces

Answer 1

Like
parallel forces are forces that are parallel and act in the same direction. If
there are two forces F1 and F2, then the resultant force R  = F1 + F2.


Unlike parallel forces are forces that are parallel and act in opposite directions. If there are two forces F1 and F2, then the resultant force R  = -F1 + F2 where the negative force is the force acting in the
