  2. AP Physics 2 - Wikipedia

    en.wikipedia.org/wiki/AP_Physics_2

    The AP Physics 2 classes began in the fall of 2014, with the first AP exams administered in May 2015. The courses were formed through collaboration between current Advanced Placement teachers and The College Board, with the guidance from the National Research Council and the National Science Foundation.

  3. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    For example, a person standing on the ground watching a train go past is an inertial observer. If the observer on the ground sees the train moving smoothly in a straight line at a constant speed, then a passenger sitting on the train will also be an inertial observer: the train passenger feels no motion. The principle expressed by Newton's ...

    Meanwhile, AP Physics 2 covered the other content areas. In 2020, the sound, waves, and electricity topics were removed from AP Physics 1 and moved to AP Physics 2. In 2024, the unit covering fluids was moved from AP Physics 2 to AP Physics 1, making space in the AP Physics 2 curriculum for more detail on waves and modern physics. [2]

  5. Arrow of time - Wikipedia

    en.wikipedia.org/wiki/Arrow_of_time

    In the 1928 book The Nature of the Physical World, which helped to popularize the concept, Eddington stated: . Let us draw an arrow arbitrarily. If as we follow the arrow we find more and more of the random element in the state of the world, then the arrow is pointing towards the future; if the random element decreases the arrow points towards the past.

  6. Temporal paradox - Wikipedia

    en.wikipedia.org/wiki/Temporal_paradox

    A bootstrap paradox, also known as an information loop, an information paradox, [6] an ontological paradox, [7] or a "predestination paradox" is a paradox of time travel that occurs when any event, such as an action, information, an object, or a person, ultimately causes itself, as a consequence of either retrocausality or time travel.

  7. Entropy as an arrow of time - Wikipedia

    en.wikipedia.org/wiki/Entropy_as_an_arrow_of_time

    The idea that we can remember the past and not the future is called the "psychological arrow of time" and it has deep connections with Maxwell's demon and the physics of information; memory is linked to the second law of thermodynamics if one views it as correlation between brain cells (or computer bits) and the outer world: Since such ...

  9. Jerk (physics) - Wikipedia

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

    The centripetal acceleration given by ⁠ v 2 / r ⁠ is normal to the arc and inward. When the particle passes the connection of pieces, it experiences a jump-discontinuity in acceleration given by ⁠ v 2 / r ⁠, and it undergoes a jerk that can be modeled by a Dirac delta, scaled to the jump-discontinuity.
