Explanation:
Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
Imagine a block with A pulling one way and B the other.
If A is bigger than B then obviously it will go in the direction of A.
The net force will be A-B as A is pulling it along with x but b is also pulling back with y.
