Motion Class 9 Extra Questions Short Answer Type 1. Question 1. Distinguish between speed and velocity. Speed is the ratio of distance and time. Speed is a scalar quantity. Velocity is the ratio of displacement and time. Velocity may be negative or positive. Velocity is a vector quantity.

Mechanical Engineering questions and answers (4) a(t)=a_0= constant [Q2] Recalling the equations of motion (equations 2 through 4), what is the acceleration in graphs 1 and 2? What does the y-intercept represent for each graph? Graph 1: Graph 2:.

a. Sketch a velocity-tim e graph for Chuck Wagon's motion. Use the velocity-time graph to determine the total distance traveled by Chuck Wagon during the 12 minutes of motion. b. F inally, break the motion into its two segments and use kinematic equations to determine the total distance traveled by Chuck Wagon..

The above equation is known as Second equation of motion. Third Equation of Motion. The third equation of motion is derived by substituting the value of time (t) from first equation of motion. We know from first equation of motion, `v=u+at` `=>v-u=at` `=>at=v-u` `=>t=(v-u)/a` -----(v) We know that the second equation of motion is, `s=ut+1/2at^2`.

Motion - equations and graphs The motion of objects can be analysed using equations and graphs. These tools allow other aspects of motion such as acceleration and displacement to be determined or.
