Today i will provide you learning on calculating force and this knowledge will help you to do physics practice problems. So let's learn it.
Here is a knowledge on how to calculate force. The normal force Fn is the element, perpendicular to the surface of contact, of the contact force used by, for example, the surface of a floor or wall, on an entity, stopping the entity from incoming the floor or wall. In a static state it is to poise the forces acting on the entity, like the force with which the entity pushes beside the surface & friction.
