A net force is a measure of the force being exerted on an object; zero net force means an object is at rest or moving at a constant speed.
Definition of net force:
The net force on an object is the vector sum of all individual forces acting on it.
This would be known as the net-force.
The the forces are unbalanced, that means that the net force is non-zero.
Inertia will not be affected when "net" or "net force" is zero.
2 Newtons to the North 7-5=2 Simple math =)
Net force is a vector sum of all the forces acting on the object. When forces acting on the body are balanced, their vector sum, or net force, is equal to zero.
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.
Net force is the sum of all the forces acting upon an object.
This would be known as the net-force.
Ten newtons downward, by definition.
If you combine all the forces in your problem , using vector addition, the resulting answer is the "net force" As a simple example if you have a force of 10 N pointing right and a force of 3 N pointing left then because they are in opposite directions the net force will be 7 N pointing right.
The the forces are unbalanced, that means that the net force is non-zero.
If no unbalanced force operates on an object its motion will be constant.
If the forces are balanced, then by definition the sum of the forces is zero.
An object is in equilibrium when the net force and the net torque on it are zero. to add Moment = Force X Perpendicular distance from pivot. Definition :- it states that the moment of force about an axes is equal to the sum of moments about same axes.
a simple machine is a mechanical device
That's the definition of "net force", so you might say "always". This refers to forces acting on the same object. If there are time-varying forces, the answer might be never!
Inertia will not be affected when "net" or "net force" is zero.
