2. 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).

3. Newton's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Newton's_laws_of_motion

   Newton's first law expresses the principle of inertia: the natural behavior of a body is to move in a straight line at constant speed. A body's motion preserves the status quo, but external forces can perturb this. The modern understanding of Newton's first law is that no inertial observer is privileged over any other.

4. Newton's law of universal gravitation - Wikipedia

   en.wikipedia.org/wiki/Newton's_law_of_universal...

   t. e. Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Separated objects attract and are attracted as if all their mass were concentrated ...

5. Generalized coordinates - Wikipedia

   en.wikipedia.org/wiki/Generalized_coordinates

   t. e. In analytical mechanics, generalized coordinates are a set of parameters used to represent the state of a system in a configuration space. These parameters must uniquely define the configuration of the system relative to a reference state. [1] The generalized velocities are the time derivatives of the generalized coordinates of the system.

6. Centripetal force - Wikipedia

   en.wikipedia.org/wiki/Centripetal_force

   v. t. e. A centripetal force (from Latin centrum, "center" and petere, "to seek" [1]) is a force that makes a body follow a curved path. The direction of the centripetal force is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. Isaac Newton described it as "a force by ...

7. Work (physics) - Wikipedia

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

   In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. A force is said to do positive work if it has a component in the ...

8. List of physical quantities - Wikipedia

   en.wikipedia.org/wiki/List_of_physical_quantities

   List of physical quantities. This article consists of tables outlining a number of physical quantities. The first table lists the fundamental quantities used in the International System of Units to define the physical dimension of physical quantities for dimensional analysis. The second table lists the derived physical quantities.

9. Cartesian coordinate system - Wikipedia

   en.wikipedia.org/wiki/Cartesian_coordinate_system

   Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)2 + (y − b)2 = r2 where a and b are the coordinates of the center (a, b) and r is the radius. Cartesian coordinates are named for René Descartes, whose invention of them in the 17th century revolutionized ...
