    The external forces: These are indicated by labelled arrows. In a fully solved problem, a force arrow is capable of indicating the direction and the line of action [notes 1] the magnitude; the point of application; a reaction, as opposed to an applied force, if a hash is present through the stem of the arrow

  5. Work (physics) - Wikipedia

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

    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 direction of the displacement of the point of application. A force does negative work if it has a component opposite to the ...

    If the fingers of the right hand are curled in the direction of the circular component of the current, the right thumb points to the north pole. Lorentz force: If an electric charge moves across a magnetic field, it experiences a force according to the Lorentz force, with the direction given by the right-hand rule. If the index finger ...

    The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them: [11] Diagram of two masses attracting one another = where F is the force between the masses; G is the Newtonian constant of gravitation (6.674 × 10 −11 m 3 ⋅kg −1 ⋅s −2);

  8. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    The change of motion of an object is proportional to the force impressed; and is made in the direction of the straight line in which the force is impressed. [ 15 ] : 114 By "motion", Newton meant the quantity now called momentum , which depends upon the amount of matter contained in a body, the speed at which that body is moving, and the ...
