instantaneous

Examples of instantaneous in the following topics:

• Instananeous Velocity: A Graphical Interpretation

  • Instantaneous velocity is the velocity of an object at a single point in time and space as calculated by the slope of the tangent line.
  • One way is to look at our instantaneous velocity , represented by one point on our curvy line of motion graphed with distance vs. time.

• Pictures of Modes

  • These are two snapshots of the instantaneous displacement of the plane when being driven in one of its modes.

• Rotational Kinetic Energy: Work, Energy, and Power

  • The instantaneous power of an angularly accelerating body is the torque times the angular velocity: $P = \tau \omega$.

• Connected Objects

  • Perfectly rigid connectors cannot stretch nor deform, and transfer forces instantaneously from one side of the connection to the other.

• RL Circuits

  • We know that the current through an inductor L cannot be turned on or off instantaneously.
  • However, this is also not instantaneous, since the inductor opposes the decrease in current by inducing an emf in the same direction as the battery that drove the current.

• Rotational Angle and Angular Velocity

  • The angular velocity describes the speed of rotation and the orientation of the instantaneous axis about which the rotation occurs.

• Faraday's Law of Induction and Lenz' Law

  • Energy can enter or leave, but not instantaneously.

• Human Perception of Sound

  • You might think that when something makes a noise that you hear it instantaneously but, in reality, it goes through many steps first.

• Superposition of Forces

  • Lorentz force f on a charged particle (of charge q) in motion (instantaneous velocity v).

• Gamma Decay

  • Emission of a gamma ray from an excited nuclear state typically requires only $10^{-12}$ seconds: it is nearly instantaneous.
