    The change in momentum, which is equal to the average net external force multiplied by the time this force acts. indefinite integral inductance infrasound inertia The resistance of any physical object to a change in its state of motion or rest, or the tendency of an object to resist any change in its motion. inductive reactance integral ...

  3. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    The branch of physics describing the motion of objects without reference to their cause is called kinematics, while the branch studying forces and their effect on motion is called dynamics. If an object is not in motion relative to a given frame of reference, it is said to be at rest , motionless , immobile , stationary , or to have a constant ...

  4. Aircraft dynamic modes - Wikipedia

    en.wikipedia.org/wiki/Aircraft_dynamic_modes

    With no special name, the shorter period mode is called simply the "short-period mode". The motion is a rapid pitching of the aircraft about the center of gravity, essentially an angle-of-attack variation. The short-period mode is an oscillation with a period of only a few seconds that is usually heavily damped by the existence of lifting ...

    A feature-length motion picture filmed in one long, uninterrupted take by a single camera, or edited in such a way as to give the impression that it was. opening credits (for a film) opening shot (for a scene) over cranking over the shoulder shot (OTS) Also called an over shoulder, ab tu, or third-person shot.

  6. Dynamical system - Wikipedia

    en.wikipedia.org/wiki/Dynamical_system

    The function Φ(t,x) is called the evolution function of the dynamical system: it associates to every point x in the set X a unique image, depending on the variable t, called the evolution parameter. X is called phase space or state space, while the variable x represents an initial state of the system. We often write

  7. Action (physics) - Wikipedia

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

    In physics, action is a scalar quantity that describes how the balance of kinetic versus potential energy of a physical system changes with trajectory. Action is significant because it is an input to the principle of stationary action, an approach to classical mechanics that is simpler for multiple objects. [1]

  8. Jerk (physics) - Wikipedia

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

    Jerk (also known as Jolt) is the rate of change of an object's acceleration over time. It is a vector quantity (having both magnitude and direction). Jerk is most commonly denoted by the symbol j and expressed in m/s 3 ( SI units ) or standard gravities per second ( g 0 /s).

  9. Simple harmonic motion - Wikipedia

    en.wikipedia.org/wiki/Simple_harmonic_motion

    The motion of a body in which it moves to and from about a definite point is also called oscillatory motion or vibratory motion. The time period is able to be calculated by = where l is the distance from rotation to center of mass of object undergoing SHM and g being gravitational acceleration. This is analogous to the mass-spring system.
