2. Newton's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Newton's_laws_of_motion

   Newton arrived at his set of three laws incrementally. In a 1684 manuscript written to Huygens, he listed four laws: the principle of inertia, the change of motion by force, a statement about relative motion that would today be called Galilean invariance, and the rule that interactions between bodies do not change the motion of their center of ...

3. 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.

4. Inertial frame of reference - Wikipedia

   en.wikipedia.org/wiki/Inertial_frame_of_reference

   The force F is the vector sum of all "real" forces on the particle, such as contact forces, electromagnetic, gravitational, and nuclear forces. In contrast, Newton's second law in a rotating frame of reference (a non-inertial frame of reference ), rotating at angular rate Ω about an axis, takes the form:

5. Work (physics) - Wikipedia

   en.wikipedia.org/wiki/Work_(physics)

   The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...

6. Eighth Air Force Scouting Forces - Wikipedia

   en.wikipedia.org/wiki/Eighth_Air_Force_Scouting...

   The Scouting Forces were several fighter flights formed by Eighth Air Force during World War II with a mission to check for Anti-Aircraft (flak) sites; weather conditions, and for Luftwaffe interceptor airfields and units in advance of heavy bomber missions over Occupied Europe and Nazi Germany.
