2. Acceleration - Wikipedia

   en.wikipedia.org/wiki/Acceleration

   The velocity of a particle moving on a curved path as a function of time can be written as: = () = (), with v(t) equal to the speed of travel along the path, and = (), a unit vector tangent to the path pointing in the direction of motion at the chosen moment in time.

3. 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.)

4. Distance from a point to a line - Wikipedia

   en.wikipedia.org/wiki/Distance_from_a_point_to_a...

   The distance (or perpendicular distance) from a point to a line is the shortest distance from a fixed point to any point on a fixed infinite line in Euclidean geometry. It is the length of the line segment which joins the point to the line and is perpendicular to the line. The formula for calculating it can be derived and expressed in several ways.

5. Speed - Wikipedia

   en.wikipedia.org/wiki/Speed

   The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; [2] the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is the magnitude of velocity (a vector), which indicates additionally the direction of ...

6. All India Secondary School Examination - Wikipedia

   en.wikipedia.org/wiki/All_India_Secondary_School...

   All India Secondary School Examination, commonly known as the class 10th board exam, is a centralized public examination that students in schools affiliated with the Central Board of Secondary Education, primarily in India but also in other Indian-patterned schools affiliated to the CBSE across the world, taken at the end of class 10. The board ...

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.

8. One-way speed of light - Wikipedia

   en.wikipedia.org/wiki/One-way_speed_of_light

   The two-way speed of light is the average speed of light from one point, such as a source, to a mirror and back again. Because the light starts and finishes in the same place, only one clock is needed to measure the total time; thus, this speed can be experimentally determined independently of any clock synchronization scheme.

9. Regularity rally - Wikipedia

   en.wikipedia.org/wiki/Regularity_rally

   A regularity rally, also called time-speed-distance or TSD rally, is a type of motorsport rally with the object of driving each segment of a course in a specified time at a specified average speed. The rally is usually conducted on public roads, but sometimes includes off-road and track sections.
