  2. Inclined plane - Wikipedia

    en.wikipedia.org/wiki/Inclined_plane

    This is the condition for impending motion up the inclined plane. If the applied force F i is greater than given by this equation, the load will move up the plane. Downhill motion: The total force on the load is toward the downhill side, so the frictional force is directed up the plane.

  3. Force - Wikipedia

    en.wikipedia.org/wiki/Force

    The SI unit of force is the newton (symbol N), which is the force required to accelerate a one kilogram mass at a rate of one meter per second squared, or kg·m·s −2.The corresponding CGS unit is the dyne, the force required to accelerate a one gram mass by one centimeter per second squared, or g·cm·s −2. A newton is thus equal to ...

  4. List of equations in classical mechanics - Wikipedia

    en.wikipedia.org/wiki/List_of_equations_in...

    Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2] The subject is based upon a three-dimensional Euclidean space with fixed axes, called a frame of ...

  5. Friction - Wikipedia

    en.wikipedia.org/wiki/Friction

    If the object is on a tilted surface such as an inclined plane, the normal force from gravity is smaller than , because less of the force of gravity is perpendicular to the face of the plane. The normal force and the frictional force are ultimately determined using vector analysis, usually via a free body diagram.

  6. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    For example, a free body diagram of a block sitting upon an inclined plane can illustrate the combination of gravitational force, "normal" force, friction, and string tension. [ note 4 ] Newton's second law is sometimes presented as a definition of force, i.e., a force is that which exists when an inertial observer sees a body accelerating.

  7. Frictionless plane - Wikipedia

    en.wikipedia.org/wiki/Frictionless_plane

    The frictionless plane is a concept from the writings of Galileo Galilei. In his 1638 The Two New Sciences, [1] Galileo presented a formula that predicted the motion of an object moving down an inclined plane. His formula was based upon his past experimentation with free-falling bodies. [2]

  8. Stokes' law - Wikipedia

    en.wikipedia.org/wiki/Stokes'_law

    Creeping flow past a falling sphere in a fluid (e.g., a droplet of fog falling through the air): streamlines, drag force F d and force by gravity F g. At terminal (or settling) velocity, the excess force F e due to the difference between the weight and buoyancy of the sphere (both caused by gravity [7]) is given by:

  9. Equations of motion - Wikipedia

    en.wikipedia.org/wiki/Equations_of_motion

    There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.
