A net force of zero means that an object behaves as if there are no forces acting upon it, although this may not be the case. Usually objects have many forces acting upon them. Just your computer that is sitting on your desk is experiencing a force of gravity, the force from the table pushing up on the computer, a frictional force holding the computer in place, etc. We can add the effects of these forces to determine one force that produces the same effect as every force that acts upon the object. This is called the principle of superpostion, which states that every force can be added to other forces to find a single net force. In the case of the computer, the force of gravity is cancelled out by the force of the table pushing up on the computer. So far we have zero force. The force of friction will resist any force that you exert upon the computer, so that force is also zero. As long as your computer is at rest and not sliding across the table, it is experiencing zero net force, while there are really many forces acting upon it.
An unbalance force means that the total force acting on an object, also known as the net force, is not equal to zero.
Zero
The basic equation is: force equals mass times acceleration.
Unless acted on by an unbalanced force, an object will maintain a constant velocity
"unbalanced"
It is in equilibrium.
Inertia will not be affected when "net" or "net force" is zero.
Net force is defined as the overall force acting on an object. When a cat sleeps on a table, the net force on it is zero. When a body is at rest the net force acting on the body is zero.
When an objects net force is zero, its acceleration is zero. No force , no acceleration.
The the forces are unbalanced, that means that the net force is non-zero.
Zero net force is when the forces are balanced and there is no acceleration.
EF=0 means when the net force on something is 0 (zero).
When forces are balanced, the net force is zero.
net force
0; zero net force
Zero
If the net force is not zero then the object will move in the direction of the greater force.
