If the acceleration = 0, meaning the resultant force = 0. provided the body is already in motion.

aaa so ht means if a object is moving its not important tht a resultant force is acting on it....???? i m really confused....i think tht acceleraion is 0...but there is a resultant force becaz object is moving in a direction...in a straioght line....steady speed..

OK, here:
No resultant force: either object at rest, or object moving at CONSTANT speed.
Resultant force: acceleration at the same direction as resultant force.
Got that? :D

A@di. From 2009 onwards the first question is ALWAYS experimental. They ask us to plan some experiment.
Can you list all the COMMON IGCSE Physics Experiments we should know....
Much appreciated man ! ;)

However, resultant force causes an accelleration. it is not the same
--- End quote ---
so if accelaration is 0...resultant force is 0???
