Force is best defined as the change of an object’s motion and possible direction due to an interaction. It will go unopposed. Velocity is the main thing that changes when a force occurs. The mass usually doesn’t change. The most common forces in physics are known to be pulls and pushes.
There is a formula for force and it is force is equal to mass times acceleration. Therefore, you can find the force of an object by knowing how much it weighs and multiplying it by the speed of its acceleration.
At first, two spheres are sixteen centimeters apart and then they are moved to eight centimeters apart, their force will increase by four, but there is no way to tell the exact calculation because the mass is unknown.
