  2. Time derivative - Wikipedia

    en.wikipedia.org/wiki/Time_derivative

    Even higher derivatives are sometimes also used: the third derivative of position with respect to time is known as the jerk. See motion graphs and derivatives. A large number of fundamental equations in physics involve first or second time derivatives of quantities. Many other fundamental quantities in science are time derivatives of one another:

  3. Second derivative - Wikipedia

    en.wikipedia.org/wiki/Second_derivative

    The last expression is the second derivative of position (x) with respect to time. On the graph of a function, the second derivative corresponds to the curvature or concavity of the graph. The graph of a function with a positive second derivative is upwardly concave, while the graph of a function with a negative second derivative curves in the ...

  4. Motion graphs and derivatives - Wikipedia

    en.wikipedia.org/wiki/Motion_graphs_and_derivatives

    Since the velocity of the object is the derivative of the position graph, the area under the line in the velocity vs. time graph is the displacement of the object. (Velocity is on the y-axis and time on the x-axis. Multiplying the velocity by the time, the time cancels out, and only displacement remains.)

  5. Fourth, fifth, and sixth derivatives of position - Wikipedia

    Snap, [6] or jounce, [2] is the fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time. [4] Equivalently, it is the second derivative of acceleration or the third derivative of velocity, and is defined by any of the following equivalent expressions: = ȷ = = =.

  6. Jerk (physics) - Wikipedia

    [12] [13] The seventh derivative is known as "Bang," as it is a logical continuation to the cycle. The eighth derivative has been referred to as "Boom," and the 9th is known as "Crash." [citation needed] However, time derivatives of position of higher order than four appear rarely. [14]

  7. Two-body problem - Wikipedia

    en.wikipedia.org/wiki/Two-body_problem

    The two dots on top of the x position vectors denote their second derivative with respect to time, or their acceleration vectors. Adding and subtracting these two equations decouples them into two one-body problems, which can be solved independently. Adding equations (1) and results in an equation describing the center of mass motion.

  8. Differential calculus - Wikipedia

    en.wikipedia.org/wiki/Differential_calculus

    velocity is the derivative (with respect to time) of an object's displacement (distance from the original position) acceleration is the derivative (with respect to time) of an object's velocity, that is, the second derivative (with respect to time) of an object's position. For example, if an object's position on a line is given by

  9. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    The time derivatives of the position and momentum variables are given by partial derivatives of the Hamiltonian, via Hamilton's equations. [ 18 ] : 203 The simplest example is a point mass m {\displaystyle m} constrained to move in a straight line, under the effect of a potential.
