Ok so my teacher has recently covered this chapter, but one of the concepts that has been bugging me for ages. Fr an object to experience zero acceleration, the forces acting on it have to be balanced. That means tha applied force has to equal the frictional force so that the resultant force will be zero. But why, if the forces are balanced, won't they cancel out each other, and leave no force to actually cause the object to more at constant speed?yes I know that according to newtons second law, no net force equal zero acceleration, but where Does the object get its energy to do work? Ie remain at constant velo.i just can't seem to understand how, and my teacher doesnt want to answer my stupid question, so all help is greatly appreciated! Oh by the way, when there is a resultant force acting on a object, will the applied force still be acting on the same object? No right ?
