A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
There can well be forces acting on the body. It means that the NET FORCE (the vector sum of all the forces) acting on the object is zero.
That's known as a free body diagram.
Net force is the vector sum of all forces acting on the object.
Equilibrium is a state in which all forces acting on an object are in balance.
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
resultant or net force
There can well be forces acting on the body. It means that the NET FORCE (the vector sum of all the forces) acting on the object is zero.
I'd call it the resultant, but "net force" is a good name too.
The force is said to be "equilibrant" when acting with other forces it would keep the body at rest ie in equilibrium. Hence equilibrant would be equal in magnitude but opposite in direction to the resultant of all the forces acting on the body.
The relationship is given by Newton's Second Law: F=ma F (force) is the net force - this refers to the vector sum of all forces acting on a body. m is the mass, and a the acceleration - the change of velocity.
Free Body Diagram
When the forces are balanced, the net force is zero, by definition. "Net force" refers to the vector sum of all the forces acting on an object.
That's known as a free body diagram.
The net force is the vector sum of all the forces acting on a body.
Net force is the vector sum of all forces acting on the object.
Yes, when all the forces acting on a body have been resolved, the final force is known as the 'net force' acting on that body.
