Force is an important concept as it influences motion. They can be easily defined as an interaction that will change the motion of an object if unopposed. But this happens to be an extremely simple way of putting things. There are a lot of concepts and angles to this word.
Forces have both magnitude and direction, so it isn’t enough to just mention the magnitude as in 8N (8 Newton), but one has to specify the direction in which it is acting. There are contact and non-contact forces. The meaning of each can be directly derived from the words itself, contact forces are the ones in contact, air resistance, friction, tension, applied force etc. fall in this category and non-contact are the ones that don’t keep contact with each other, for instance a good example would be gravity. But one must keep in mind that inertia is not a force in itself, anything with mass exhibits inertia. The larger something is, the more force one has to apply to overcome its inertia.
Force: Push and Pull
For instance, forces have been defined as the interaction that change the motion of an object if unopposed. When this statement is examined closely, we see the role of push-pull in this. Take a force that changes the direction of an object towards you that would be a pull, since it’s approaching you. If on the other hand it moves away, then it happens to be a push. In some definitions, forces are literally defined as a push or pull upon an object resulting from the object’s interaction with another object. Hence, any kind of force is just basically a push or a pull. Springs and elastic are also types of forces, the moment you push against it; it resists and reacts or springs back with the same magnitude.
