2. Force - Wikipedia

   en.wikipedia.org/wiki/Force

   In such a situation, a force is applied in the direction of motion while the kinetic friction force exactly opposes the applied force. This results in zero net force, but since the object started with a non-zero velocity, it continues to move with a non-zero velocity. Aristotle misinterpreted this motion as being caused by the applied force.

   For example, in 1742, Émilie du Châtelet wrote, "Dead force consists of a simple tendency to motion: such is that of a spring ready to relax; living force is that which a body has when it is in actual motion." In modern terminology, "dead force" and "living force" correspond to potential energy and kinetic energy respectively. [137]

4. Outline of physics - Wikipedia

   en.wikipedia.org/wiki/Outline_of_physics

   Physics – natural science that involves the study of matter [1] and its motion through spacetime, along with related concepts such as energy and force. [2] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. [3] [4] [5]

5. Motion - Wikipedia

   en.wikipedia.org/wiki/Motion

   A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force. (This is known as the law of inertia .) Force ( F → {\displaystyle {\vec {F}}} ) is equal to the change in momentum per change in time ( Δ m v → Δ t {\displaystyle {\frac {\Delta m{\vec {v}}}{\Delta t}}} ).

6. Mechanics - Wikipedia

   According to Shlomo Pines, al-Baghdaadi's theory of motion was "the oldest negation of Aristotle's fundamental dynamic law [namely, that a constant force produces a uniform motion], [and is thus an] anticipation in a vague fashion of the fundamental law of classical mechanics [namely, that a force applied continuously produces acceleration]." [13]

   F 2. gravitational force by object on earth (upward) F 3. force by support on object (upward) F 4. force by object on support (downward) Forces F 1 and F 2 are equal, due to Newton's third law; the same is true for forces F 3 and F 4. Forces F 1 and F 3 are equal if and only if the object is in equilibrium, and no other forces are applied ...
