    direction: unitless impact parameter meter (m) differential (e.g. ) varied depending on context differential vector element of surface area A, with infinitesimally small magnitude and direction normal to surface S: square meter (m 2) differential element of volume V enclosed by surface S

  3. Force - Wikipedia

    en.wikipedia.org/wiki/Force

    The concept of force makes the everyday notion of pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity. The SI unit of force is the newton (N), and force is often represented by the symbol F. Force plays an important role in classical mechanics.

    Stresses and strains are of no interest but rotational effects are. A force arrow should lie along the line of force, but where along the line is irrelevant. A force on an extended rigid body is a sliding vector. non-rigid extended. The point of application of a force becomes crucial and has to be indicated on the diagram.

    en.wikipedia.org/wiki/Newton_(unit)

    A newton is defined as 1 kg⋅m/s 2 (it is a named derived unit defined in terms of the SI base units). [1]: 137 One newton is, therefore, the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.

  6. Right-hand rule - Wikipedia

    en.wikipedia.org/wiki/Right-hand_rule

    The bending force is computed by the vector cross-product. This means that the bending force increases with the velocity of the particle and the strength of the magnetic field. The force is maximum when the particle direction and magnetic fields are perpendicular, is less at any other angle, and is zero when the particle moves parallel to the ...

    Quantity Unit Remarks Name Symbol Name Symbol Definition Force: F: newton: N 1 N = 1 kg·m/s 2: Unit named after Isaac Newton: Moment of force, Torque: M, : N·m 1 N·m = 1 kg·m 2 /s 2: The unit is dimensionally equivalent to the units of energy, the joule; but the joule should not be used as an alternative for the newton metre.

  8. Torque - Wikipedia

    en.wikipedia.org/wiki/Torque

    In three dimensions, the torque is a pseudovector; for point particles, it is given by the cross product of the displacement vector and the force vector. The direction of the torque can be determined by using the right hand grip rule: if the fingers of the right hand are curled from the direction of the lever arm to the direction of the force ...
