How do you Determine the net force?

Answer 1

You can calculate the net force in two different ways, it all depends on the information that you are given in your question. First way to calculate you net force is using the formula:

Fnet (bring the net force)= m(being the mass to the object in Kg)*a(being the acceleration of the object in m/s^2)

So the formula is Fnet = ma

The second way to find net force is by adding all of the acting forces together. For example to find the net force of a person pushing a box, and you are given the applied force and force of friction, you can use the equation:

Fnet(being the net force)= Fa(being the applied force) + Ff (being the force of friction)

Keep in mind that one of the forces will be negative, depending on the direction.

So the formula is Fnet=Fa+Ff

Answer 2

First the net force is the sum of all the forces acting on a body. Because a force has direction as well as magnitude it is a vector and you need to add the forces vectorally. As a general rule you beak the force up into components and then add the components together.

Answer 3

Measure net force upon an object by adding all of the individual forces acting upon the object.

Remember that force is a vector, meaning that it has a magnitude AND a direction. Therefore, forces in opposite directions essentially subtract, and forces in the same direction add.

Answer 4

The answer depends on whether the forces are acting at the same point of different points.

If at the same point you can either draw up a polygon (polyhedron) representing the vector addition. Alternatively, you could select a pair (or trio) of orthogonal axes in 2 dimensional (3d) space and decompose each vector into its components along these axes. The signed addition of the vecors along each axis can be computed easily to give the 2 (or 3) resultant forces. These can be added together using vector addition.

However, if the forces act at different points on an extended object, you need to take the moments of the force into consideration. These can be calculated for various locations on the object. The moments of a force is the magnitude of the force multiplied by the vertical distance from the line of action of the force to the reference point, and the moment is either clockwise or anticlockwise.

Answer 5

NET FORCE IS THE TOTAL FORCE JUST CALCULATE ALL THE Y,X FORCES

Answer 6

You can calculate the net force by finding the sum of all the forcing acting on an object, or use the forumula: Fnet = ma (net force equals mass times acceleration).

Answer 7

The net force is defined as the vector sum of all the forces on an object. If you know the individual forces, you just add them together (using the rules for vectors, of course).
