Test: Uniform Circular Motion - Question 1

In a uniform circular motion - 

Detailed Solution for Test: Uniform Circular Motion - Question 1

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.

Test: Uniform Circular Motion - Question 2

In circular motion, the

Detailed Solution for Test: Uniform Circular Motion - Question 2

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.

Test: Uniform Circular Motion - Question 3

Uniform circular motion is called continuously accelerated motion mainly because

Test: Uniform Circular Motion - Question 4

In circular motion:

Test: Uniform Circular Motion - Question 5

For a particle in a non- uniform accelerated circular motion 

Detailed Solution for Test: Uniform Circular Motion - Question 5
  • Velocity is transverse (t): This is because the velocity is always tangent to the circle.
  • Acceleration has both radial and transverse components: The acceleration has a radial component (directed along the radius, responsible for maintaining circular motion) and a transverse component (directed tangentially, responsible for changes in speed).
*Multiple options can be correct
Test: Uniform Circular Motion - 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

*Multiple options can be correct
Test: Uniform Circular Motion - Question 7

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

Detailed Solution for Test: Uniform Circular Motion - Question 7

 

Therefore, the correct multiple answers are:

2. Uniform, constant
3. Non-uniform, varying

  • Non-uniform, constant – This is incorrect. If the motion is non-uniform, the speed cannot be constant.

  • Uniform, constant – This is correct. In uniform circular motion, the speed is constant.

  • Non-uniform, varying – This is correct. In non-uniform circular motion, the speed varies.

  • Uniform, varying – This is incorrect. If the motion is uniform, the speed must remain constant, so it cannot be varying.

Test: Uniform Circular Motion - Question 8

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

Detailed Solution for Test: Uniform Circular Motion - Question 8

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

Test: Uniform Circular Motion - Question 9

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

Detailed Solution for Test: Uniform Circular Motion - Question 9

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.

Test: Uniform Circular Motion - Question 10

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

Detailed Solution for Test: Uniform Circular Motion - Question 10

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.
