  2. Derivative work - Wikipedia

    en.wikipedia.org/wiki/Derivative_work

    The musical West Side Story, is a derivative work based on Shakespeare's Romeo and Juliet, because it uses numerous expressive elements from the earlier work. [42] However, Shakespeare's drama Romeo and Juliet is also a derivative work that draws heavily from Pyramus and Thisbe and other sources. Nevertheless, no legal rule prevents a ...

  3. Work (physics) - Wikipedia

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

    The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...

    The derivative of ′ is the second derivative, denoted as ⁠ ″ ⁠, and the derivative of ″ is the third derivative, denoted as ⁠ ‴ ⁠. By continuing this process, if it exists, the ⁠ n {\displaystyle n} ⁠ th derivative is the derivative of the ⁠ ( n − 1 ) {\displaystyle (n-1)} ⁠ th derivative or the derivative of order ...

    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

  6. Differential (mathematics) - Wikipedia

    If the derivative f vanishes at p, then f − f(p) belongs to the square I p 2 of this ideal. Hence the derivative of f at p may be captured by the equivalence class [f − f(p)] in the quotient space I p /I p 2, and the 1-jet of f (which encodes its value and its first derivative) is the equivalence class of f in the space of all functions ...

    The word derivative sounds fancy and perhaps a little intimidating. But the key thing to know about derivatives is that they are a financial contract whose value is derived from the value of ...

  8. Power (physics) - Wikipedia

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

    Power is the rate with respect to time at which work is done; it is the time derivative of work: =, where P is power, W is work, and t is time. We will now show that the mechanical power generated by a force F on a body moving at the velocity v can be expressed as the product: P = d W d t = F ⋅ v {\displaystyle P={\frac {dW}{dt}}=\mathbf {F ...
