QUESTION: 1

In a uniform circular motion -

Solution:

For a body moving in uniform circular motion the speed attained  by the object will remain constant not the velocity as velocity depends on the direction of motion, and in circular motion the direction of the object changes at every point. As speed remains constant the acceleration will remain constant.

QUESTION: 2

In circular motion, the

Solution:

When an object moves along a circular path, it is called circular motion. During such a motion, the direction of motion at any point is given by the tangent at that point which changes continuously.

QUESTION: 3

Uniform circular motion is called continuously accelerated motion mainly because

Solution:
QUESTION: 4

In circular motion:

Solution:
QUESTION: 5

For a particle in a non- uniform accelerated circular motion

Solution:
*Multiple options can be correct
QUESTION: 6

A particle is acted upon by a force of constant magnitude. Which is always perpendicular to the velocity of the particle ? The motion of the particle takes place in a plane. It follow that that

Solution:
*Multiple options can be correct
QUESTION: 7

The _______ circular motion describes as the motion of an object in a circular path with a _______ speed. Fill in the blank.

Solution:

The object is said to be in an uniform circular motion if the speed of the object moving in the circular path is constant.
Whereas the object is said to be in a non-uniform circular motion if the speed of the object moving in the circular path is varying (either increasing or decreasing).

QUESTION: 8

Uniform circular motion is called continuously accelerated motion mainly because its :

Solution:

An accelerating body is an object that is changing its velocity. And since velocity is a vector that has both magnitude and direction, a change in either the magnitude or the direction constitutes a change in the velocity.
Hence a uniform circular motion is a accelerated motion because direction of motion keeps on changing

QUESTION: 9

A particles revolves along a circle with a uniform speed. The motion of the particle is ____ .

Solution:

To describe the motion of a particle along a circle with a uniform speed. We need two variable, either x and y, or r and θ. Therefore, the motion of the particle is two-dimensional.

QUESTION: 10

Which one of the following is most probably not a case of uniform circular motion?

Solution:

An object moving in uniform circular motion is moving in a circle with a uniform or constant speed. The velocity vector is constant in magnitude but changing in direction.
Hence, the motion of a racing car on a circular track changes it speed, that is, it increases or decreases speed during the drive not a case of uniform circular motion.
