  2. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    Consequently, the acceleration is the second derivative of position, [7] often written . Position, when thought of as a displacement from an origin point, is a vector: a quantity with both magnitude and direction. [9]: 1 Velocity and acceleration are vector quantities as well. The mathematical tools of vector algebra provide the means to ...

  3. Jerk (physics) - Wikipedia

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

    The jump in acceleration equals the force on the mass divided by the mass. That is, each time the mass passes through a minimum or maximum displacement, the mass experiences a discontinuous acceleration, and the jerk contains a Dirac delta until the mass stops.

  4. Momentum - Wikipedia

    en.wikipedia.org/wiki/Momentum

    hence the net force is equal to the mass of the particle times its acceleration. [1] Example: A model airplane of mass 1 kg accelerates from rest to a velocity of 6 m/s due north in 2 s. The net force required to produce this acceleration is 3 newtons due north. The change in momentum is 6 kg⋅m/s due north.

  5. Equations of motion - Wikipedia

    en.wikipedia.org/wiki/Equations_of_motion

    Analogous to mass times acceleration, the moment of inertia tensor I depends on the distribution of mass about the axis of rotation, and the angular acceleration is the rate of change of angular velocity, =.

  6. Acceleration - Wikipedia

    en.wikipedia.org/wiki/Acceleration

    In classical mechanics, for a body with constant mass, the (vector) acceleration of the body's center of mass is proportional to the net force vector (i.e. sum of all forces) acting on it (Newton's second law): = =, where F is the net force acting on the body, m is the mass of the body, and a is the center-of-mass acceleration.

  7. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    For a constant mass, force equals mass times acceleration (=). For every action, there is an equal and opposite reaction. (In other words, whenever one body exerts a force F → {\displaystyle {\vec {F}}} onto a second body, (in some cases, which is standing still) the second body exerts the force − F → {\displaystyle -{\vec {F}}} back onto ...

  8. Historical definitions of the SI base units - Wikipedia

    en.wikipedia.org/wiki/Historical_definitions_of...

    Mass, strictly the inertial mass, represents a quantity of matter. It relates the acceleration of a body to the applied force via Newton's law, F = m × a: force equals mass times acceleration. A force of 1 N (newton) applied to a mass of 1 kg will accelerate it at 1 m/s 2. This is true whether the object is floating in space or in a gravity ...

  9. Metre per second squared - Wikipedia

    en.wikipedia.org/wiki/Metre_per_second_squared

    Newton's second law states that force equals mass multiplied by acceleration. The unit of force is the newton (N), and mass has the SI unit kilogram (kg). One newton equals one kilogram metre per second squared. Therefore, the unit metre per second squared is equivalent to newton per kilogram, N·kg −1, or N/kg. [2]
