## What is Force?

That vector magnitude by which a body can be set in motion, deformed, or modified in velocity is known under the name force. This is capable of transforming the state of rest or movement of a body and is measured in Newtons (N).

There are different types of forces, some of them are: Elastic force: it is the one that the springs manage to exert that, out of their normal position, that is, when they are compressed or stretched and they manage to exert force, either by pushing or pulling a body. Friction force: is the contact force that arises when a body is slid on a surface and opposes this movement. Within this force, we find two types: the dynamic and the static. Static force establishes the minimum force required to move a body. This force is equivalent to the force needed to move a body, although in the opposite direction. The force that opposes the movement of a body is that of dynamic friction. Normal force: it is one that exerts a surface when it reacts to a body that slides on it.
