2. Motion graphs and derivatives - Wikipedia

   en.wikipedia.org/wiki/Motion_graphs_and_derivatives

   Motion graphs and derivatives. The green line shows the slope of the velocity-time graph at the particular point where the two lines touch. Its slope is the acceleration at that point. In mechanics, the derivative of the position vs. time graph of an object is equal to the velocity of the object. In the International System of Units, the ...

3. Spacetime diagram - Wikipedia

   en.wikipedia.org/wiki/Spacetime_diagram

   Unlike a regular distance-time graph, the distance is displayed on the horizontal axis and time on the vertical axis. Additionally, the time and space units of measurement are chosen in such a way that an object moving at the speed of light is depicted as following a 45° angle to the diagram's axes.

4. Velocity - Wikipedia

   en.wikipedia.org/wiki/Velocity

   Velocity is a physical vector quantity: both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s −1). For example, "5 metres per second" is a scalar, whereas "5 ...

5. Speed - Wikipedia

   en.wikipedia.org/wiki/Speed

   L T−1. In kinematics, the speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a non-negative scalar quantity. [1] The average speed of an object in an interval of time is the distance travelled by the object divided ...

6. 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 (g0 /s).

7. Time–distance diagram - Wikipedia

   en.wikipedia.org/wiki/Time–distance_diagram

   A time–distance diagram is a chart with two axes: one for time, the other for location. The units on either axis depend on the type of project: time can be expressed in minutes (for overnight construction of railroad modification projects such as the installation of switches) or years (for large construction projects); the location can be (kilo)meters, or other distinct units (such as ...

8. Galileo's law of odd numbers - Wikipedia

   en.wikipedia.org/wiki/Galileo's_law_of_odd_numbers

   The graph in the figure is a plot of speed versus time. Distance covered is the area under the line. Each time interval is coloured differently. The distance covered in the second and subsequent intervals is the area of its trapezium, which can be subdivided into triangles as shown.

9. Work (physics) - Wikipedia

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

   For convenience, consider contact with the spring occurs at t = 0, then the integral of the product of the distance x and the x-velocity, xv x dt, over time t is ⁠ 1 / 2 ⁠ x 2. The work is the product of the distance times the spring force, which is also dependent on distance; hence the x 2 result.
