This is were we educate our readers with theory, along with everyday examples... Stuff we can all relate to.
In physics, force is an influence that may cause a body to accelerate. It may be experienced as a lift, a push, or a pull. The actual acceleration of the body is determined by the vector sum of all forces acting on it (known as net force or resultant force). In an extended body, force may also cause rotation or deformation of the body.
Hooke's law of elasticity states that the extension of an elastic body (its distended length minus its relaxed length) is linearly proportional to its tension, the force used to stretch it. Similarly, the contraction (negative extension) is proportional to the compression (negative tension).
