subtract the magnitudes
You find the difference of the forces.
Net force is when forces are added together. so the net force is 0. i have it in my science questions so i ! - Scientist
Are you asking if a non-zero net force results in a change of motion? The answer is yes. Force is defined as mass times acceleration. Acceleration is the first derivative of velocity, i.e. the rate at which velocity changes. So if the net force is not zero, the net change in velocity is not zero, which says there is a change in motion.
When you combine 2 velocities that are in the same directions, add them together to find the resultant velocity. When you combine 2 velocities that are in opposite directions, subtract the smaller velocity from the larger velocity to find the resultant velocity.
forces in the same direction can be added to give us the resultant force and opposite force will subtracted to get resultant force
(1) Decide on a direction that you will consider positive. (2) Calculate the momentum of the object that travels in the "positive" direction. (3) Calculate the momentum of the object that travels in the "negative" direction (the momentum should be negative). (4) Add both numbers algebraically.
by subbracting
In this case, you can simply subtract one force from the other.
You subtract the smaller force from the larger force and use the direction of the larger force.
You must first choose which direction you shall call positive, thereby the opposite direction shall be negative. Then you add these two values together to get your answer, the total net force.
You subtract the smaller force from the larger one.
A body accelerates when force acts on it. Actually, we should say a "net force" ... if there is more than one force acting on the body, they may have different strengths and come from different directions. Then, we have to combine their strengths and directions to find a single force that's equivalent to all the separate ones. If the strengths and directions are just right, it's possible that they can all cancel each other out ... for example, if there are two forces on the body, with equal strength and exactly opposite directions, they add up to zero, just as if there was no force at all acting on the body. So we should actually say that a body accelerates when the net force on it is not zero.

In MS-Word, you can select "Insert - Symbol" and find it there. If you need it often, you can assign a shortcut to it, with the "Autotext" feature. For other programs, you can use the CharMap utility, find the symbol there, then copy and paste.
