Frank Modern Certificate Solution for Class 10 Physics Chapter Unit - 1 - Force, Work, Energy and Power - Uniform Circular Motion Page/Excercise 25

Solution 1

When a particle moves with a constant speed in a circular path, its motion is said to be the uniform circular motion.

Solution 2

In uniform circular motion, a particle travels equal distances along the circular path in equal intervals of time, so the speed of particle is uniform. But the direction of motion of the particle changes at each point of circular path. Due to continuous change in direction of motion, the velocity of the particle is not uniform (or velocity is variable) i.e., the motion is accelerated.

Solution 3

Centripetal force: The force acting on a body moving in a circular path. It acts along the radius of the circle and towards its centre.

Solution 4

The SI unit of centripetal force is newton (N).

Solution 5

Centrifugal force is not a real force, but it is considered to describe (understand) a certain motion. It should not be considered as the force of reaction of centripetal force, although its magnitude is same as that of centripetal force.

Solution 6

In uniform linear motion, the velocity is constant and acceleration is zero i.e., the uniform linear motion is an un-accelerated motion, while in a uniform circular motion the velocity is variable (although speed is uniform), so it is an accelerated motion.

Solution 7

The force needed for circular motion is 'centripetal force'.
This force is always directed towards the centre of circle at each point of its path.

Solution 8

(b) speed

Solution 9

Yes, it is an accelerated motion.

Solution 10

No, the earth moves round the sun with a variable velocity. Since the direction of motion changes at each and every point the velocity becomes variable.

Solution 11

Centripetal force has a reaction force in accordance with the Newton's third law of motion. This oppositely directed force is called centrifugal force.

Solution 12

Centrifugal force acts away from the centre of circular path.
