External forces can be divided into contact forces and non-contact forces. Most forces that biomechanics works with are contact forces. Contact forces are forces that act at the point of contact between two objects. Gravitational force, acting on all objects on the Earth, is a non-contact force.

Answer 2

Answer:

A force is a push or pull acting upon an object as a result of its interaction with another object. ... Previously in this lesson, a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects.
