2. Velocity - Wikipedia

   en.wikipedia.org/wiki/Velocity

   While the terms speed and velocity are often colloquially used interchangeably to connote how fast an object is moving, in scientific terms they are different. Speed, the scalar magnitude of a velocity vector, denotes only how fast an object is moving, while velocity indicates both an object's speed and direction. [3] [4] [5]

3. Worksheet - Wikipedia

   en.wikipedia.org/wiki/Worksheet

   It can be a printed page that a child completes with a writing instrument. No other materials are needed. In education, a worksheet may have questions for students and places to record answers. In accounting, a worksheet is, or was, a sheet of ruled paper with rows and columns on which an accountant could record information or perform calculations.

4. Speed - Wikipedia

   en.wikipedia.org/wiki/Speed

   Average speed does not describe the speed variations that may have taken place during shorter time intervals (as it is the entire distance covered divided by the total time of travel), and so average speed is often quite different from a value of instantaneous speed. [3] If the average speed and the time of travel are known, the distance ...

5. Mathematics - Wikipedia

   en.wikipedia.org/wiki/Mathematics

   In the present day, the distinction between pure and applied mathematics is more a question of personal research aim of mathematicians than a division of mathematics into broad areas. [ 124 ] [ 125 ] The Mathematics Subject Classification has a section for "general applied mathematics" but does not mention "pure mathematics". [ 14 ]

6. Newton's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Newton's_laws_of_motion

   The speed attained during free fall is proportional to the elapsed time, and the distance traveled is proportional to the square of the elapsed time. [40] Importantly, the acceleration is the same for all bodies, independently of their mass. This follows from combining Newton's second law of motion with his law of universal gravitation.

7. Jerk (physics) - Wikipedia

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

   It is reported [9] that most passengers rate a vertical jerk of 2 m/s 3 as acceptable and 6 m/s 3 as intolerable. For hospitals, 0.7 m/s 3 is the recommended limit. A primary design goal for motion control is to minimize the transition time without exceeding speed, acceleration, or jerk limits.
