Velocity-Time Graph For Non-Uniform Accelerated Motion

Concept Explanation

Velocity-Time Graph For Non-Uniform Accelerated Motion

(iii) Velocity-Time Graph for Non-uniform Accelerated Motion

Velocity-time graph for non-uniform accelerated motion is shown :

It shows that the variation of velocity of a body (or object) varies non-uniformly with time.

Example: The velocity -time graph of an ascending passenger lift is shown iin figure below. What is the acceleration of the lift

(i) during the first two seconds?

(ii) between 2nd and 10th second?

(iii) during the last two seconds?

SOLUTION

(i) Case I

$large Delta v=4-0=4m/s,$

$large Delta t=2-0=2s,$

$large a_{1}=?$

$large therefore a_{1}=frac{Delta v}{Delta t}=frac{4}{2}=2;;;m/s^{2}$

(ii) Case II

$large Delta v=4.6-4=0.6m/s, Delta t=10-2=8s,a_{2}=?$

$large because a_{2}=frac{Delta v}{Delta t}$

$large =frac{0.6}{8}=0.075;m/s^{2}$

(iii) Case III

$large Delta v=0-4.6=-4.6m/s,Delta t=12-10=2s,a_{3}=?$

$large therefore a_{3}=frac{Delta v}{Delta t}=frac{-4.6}{2}=-2.3;m/s^{2}$

Negative sign shown retardation.

My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
