When a particle moves with a constant speed in a circular path. its motion is said to be the uniform circular motion. For example Revolution of the earth around the sun is an example of uniform circular motion.

## Why is it called uniform circular motion?

Uniform circular motion : When a body moves in a circular path with uniform speed (constant speed), its motion is called uniform circular motion. When a body moves in a circle, its direction changes continuously. Due to this change in direction we say that velocity changes and the motion is accelerated.

## What is uniform circular motion Vedantu?

Hint:Uniform circular motion means that the particle or an object or a body which moves or travels in the circular path, with the uniform acceleration. Uniform acceleration is the acceleration of the object or body or a particle is constant.

## What is uniform circular motion write its any two characteristics?

A particle in uniform circular motion is identified by two characteristics: It is moving at a constant speed v and is moving in a circular path with a radius r. Then the acceleration of the particle is directed radially toward the center of the circular path and has magnitude v2/r.

## Who Found uniform circular motion?

On Uniform Circular Motion. Isaac Newton was born on 25 December 1642, in the manor house of Woolsthorpe, a very small village seven miles south of the town of Grantham.

## What is circular motion in simple words?

Circular motion is described as a movement of an object while rotating along a circular path. Circular motion can be either uniform or non-uniform. During uniform circular motion the angular rate of rotation and speed will be constant while during non-uniform motion the rate of rotation keeps changing.

## Why is uniform circular motion important?

A very important case of changing direction while maintaining constant speed is called uniform circular motion. In that case, the object’s speed remains constant, hence “uniform”, while its direction is constantly changing, this is necessary to keep it moving in a circle.

## What is uniform circular motion Class 9 Example?

Solution : When a point object is moving on a circular path with a constant speed, it covers equal distances on the circumference of the circle in equal intervals of time . Then the object is said to be in uniform circular motion .

Examples :

(i) Motion of the tip of the second hand of clock .

## How do you show uniform circular motion?

## How do you derive uniform circular motion?

Centripetal Acceleration (α) = v2/r = rῶ2. The magnitude of this acceleration by comparing ratios of velocity and position around the circle. Since the particle is traveling in a circular path, the ratio of the change in velocity to velocity will be the same as the ratio of the change in position to position.

## What is uniform circular motion class11?

What is Uniform Circular Motion? The movement of a body following a circular path is called a circular motion. Now, the motion of a body moving with constant speed along a circular path is called Uniform Circular Motion.

## What is meant by uniform circular motion class 11?

(a) When a body moves in a circular path with uniform speed (constant speed), its motion is called uniform circular motion.

## Is uniform circular motion is SHM?

In case of uniform circular motion, no restoring force acts on the body. So it can not be called a SHM.

## What are the characteristics of uniform circular motion class 9?

- Characteristics of U.C.M:
- i. It is a periodic motion with definite period and frequency.
- ii. Speed of particle remains constant but velocity changes continuously.
- iii. It is an accelerated motion.
- iv. Work done in one period of U.C.M is zero.

## What is characteristic of uniform circular?

An important characteristic of uniform circular motion is that the direction of motion in it changes continuously with time, so it is accelerated. Centripetal force brings about uniform circular motion.

## What are the characteristics of uniform motion?

Speed must be constant. Object travels equal distance in equal intervals of time. Speed increases with time. No worries!

## Is a car is example of uniform circular motion?

A car is taking a curve turn on a circular path at a constant speed. This is definitely an example of a uniform circular motion as the car is moving at a constant velocity and in a circular path.

## How many types of circular motion are there?

There are two types of circular motion mentioned below: Uniform circular motion. Non-uniform circular motion.

## What is circular motion is also called?

In a circular motion, there is a continuous change in the direction of motion. The velocity changes when the direction changes. Therefore, circular motion is an accelerated motion.

## Which of the following is an example of uniform circular motion?

Motion of a satellite in circular orbit is an example of uniform circular motion.

## What is the time in a uniform circular motion?

When an object is experiencing uniform circular motion, it is traveling in a circular path at a constant speed. If r is the radius of the path, and we define the period, T, as the time it takes to make a complete circle, then the speed is given by the circumference over the period.

## What is zero in a uniform motion?

Zero uniform velocity motion implies uniform velocity with zero acceleration. It’s the object being at rest with respect to you since you are the one who sees it with zero velocity. Was this answer helpful?

## What is non uniform circular motion Class 9 Example?

For example, when the bob attached to a string moves in a vertical circle, the speed of the bob is not the same at all times Whenever the speed is not the same in a circular motion, the particle will have both centripetal and tangential acceleration.

## What is uniform circulation method Class 9?

Uniform circular motion: When an object moves on a circular path with constant or uniform speed, it is said to have uniform circular motion.

## What is non uniform circular motion class 9?

Non-uniform circular motion is a circular motion when the speed of the body doesn’t remain constant. The body has both normal as well as tangential acceleration.
