- $\text{C}$
- $\text{E}$
- $\text{D}$
- $\text{F}$

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
At $E,$ the slope of the curve is negative, i.e. for a displacement-time graph the slope represents the velocity and at $E,$ the velocity is $- \text{v} \text{e}$ as the slope is $- \text{v} \text{e}$ .

Motion in a straight line
The motion in a straight line is an object changes its position with respect to its surroundings with time, then it is called in motion. It is a change in the position of an object over time. It is nothing but linear motion.
Types of Linear Motion:
Linear motion is also known as the Rectilinear Motion which are of two types:
- Uniform linear motion with constant velocity or zero acceleration: If a body travels in a straight line by covering an equal amount of distance in an equal interval of time then it is said to have uniform motion.
- Non-Uniform linear motion with variable velocity or non-zero acceleration: Not like the uniform acceleration, the body is said to have a non-uniform motion when the velocity of a body changes by unequal amounts in equal intervals of time. The rate of change of its velocity changes at different points of time during its movement.
