Question:
If a particle moves in a circle describing equal angles in equal intervals of times, the velocity vector
If a particle moves in a circle describing equal angles in equal intervals of times, the velocity vector
Updated On: Jul 6, 2022
- remains constant
- change in magnitude
- changed in direction
- changed both in magnitude and direction
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The figure clearly describes motion of the particles and it is evident that the velocity vector changes direction continuously during the motion. As the particle is covering equal angles in equal time, the magnitude remains constant while the direction changes.

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.
