2. Newton's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Newton's_laws_of_motion

   [9]: 4 The study of mechanics is complicated by the fact that household words like energy are used with a technical meaning. [10] Moreover, words which are synonymous in everyday speech are not so in physics: force is not the same as power or pressure, for example, and mass has a different meaning than weight.

3. The Feynman Lectures on Physics - Wikipedia

   en.wikipedia.org/.../The_Feynman_Lectures_on_Physics

   The Feynman Lectures on Physics. The Feynman Lectures on Physics is a physics textbook based on a great number of lectures by Richard Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". [1] The lectures were presented before undergraduate students at the California Institute of Technology (Caltech), during 1961–1964.

5. Free body diagram - Wikipedia

   en.wikipedia.org/wiki/Free_body_diagram

   In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body (ies).

6. Mathematics - Wikipedia

   en.wikipedia.org/wiki/Mathematics

   Mathematics is a field of study that discovers and organizes methods, theories and theorems that are developed and proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study ...

7. Branches of physics - Wikipedia

   en.wikipedia.org/wiki/Branches_of_physics

   It deals with the motion of particles and the general system of particles. There are many branches of classical mechanics, such as: statics, dynamics, kinematics, continuum mechanics (which includes fluid mechanics), statistical mechanics, etc. Mechanics: A branch of physics in which we study the object and properties of an object in form of a ...

8. List of unsolved problems in physics - Wikipedia

   en.wikipedia.org/wiki/List_of_unsolved_problems...

   The following is a list of notable unsolved problems grouped into broad areas of physics. [ 1 ] Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in ...

9. Free fall - Wikipedia

   en.wikipedia.org/wiki/Free_fall

   Free fall. In classical mechanics, free fall is any motion of a body where gravity is the only force acting upon it. A freely falling object may not necessarily be falling down in the vertical direction. An object moving upwards might not normally be considered to be falling, but if it is subject to only the force of gravity, it is said to be ...
