**velocity changes when the direction changes**. Therefore, circular motion is an accelerated motion.

Uniform circular motion is accelerated because the velocity changes due to continuous change in the direction of motion. … Therefore, circular motion is an **acceleration motion** even when the speed remains constant. An accelerating body is an object that is changing its velocity.

When an object moves in a circular track/path with uniform speed, it’s motion is called uniform circular motion. example – if the athlete moves with a velocity of constant magnitude along the circular path the only change in his velocity is due to the change in the direction of the motion.

**centripetal acceleration**, the acceleration of a body traversing a circular path. Because velocity is a vector quantity (that is, it has both a magnitude, the speed, and a direction), when a body travels on a circular path, its direction constantly changes and thus its velocity changes, producing an acceleration.

An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it **is accelerating due to its change in direction**. … Yet, with the inward net force directed perpendicular to the velocity vector, the object is always changing its direction and undergoing an inward acceleration.

(a) When a body moves in a circular path with uniform speed (constant speed), its motion is called uniform circular motion. For e.g. (i) Artificial satellites move in uniform circular motion around the earth. (ii) **Motion of a cyclist on a circular track**.

In a circular motion, there is a continuous change in the direction of motion. … Therefore, circular motion is an **accelerated motion**.

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.

**The movement of an object in a circular path, with a constant speed**, is known as uniform circular motion. A bike moving around a circular path is in a circular motion. The bike moving in a circular path with uniform speed is known as uniform circular motion.

rate of change of tangential velocity is called as the centripetal acceleration. **F=rmv2**. centripetal acceleration is given by, ac=mF. =mrmv2.

**ac=v2r a c = v 2 r** , which is the acceleration of an object in a circle of radius r at a speed v. So, centripetal acceleration is greater at high speeds and in sharp curves (smaller radius), as you have noticed when driving a car.

Consider a body of mass m moving along the circumference of a circle. the radius of a circle r with velocity v,as shown in the figure. Then if a small force F is applied on the body, then we know that the force is given as F=ma. … Thus, the acceleration due to centripetal force is given by,**a=v2r**.

Diagram of non-uniform circular motion: In non-uniform circular motion, the magnitude of the angular velocity changes over time. The change in direction is accounted by radial acceleration ( centripetal acceleration ), which is given by following relation: **ar=v2r a r = v 2 r** .

a_{rad} | Radial acceleration |
---|---|

T | Time Period |

V | Velocity |

C | Circumference |

Using a uniform circular motion, obtain the equation **acceleration ac = v²/r** for uniform circular motion. Consider a particle of mass, ‘m’ moving with a constant speed, ‘v” having a uniform angular velocity, ‘ω,’ around a circular path of radius, ‘r’ with center O. Let the particle be at P in any time, Since v = r × ω

In uniform linear motion, the **speed and direction of motion is fixed** and so, it is not accelerated. Example- A car running on a straight road. In uniform circular motion, the speed is constant but the direction of motion changes continuously and hence, it is accelerated. Example- Motion of earth around the sun.

**because the velocity changes as the direction is changing so the acceleration** also occurs that’s why it’s called as accelerated motion.

By definion , acceleration is rate of change of velocity , | Δv | / Δt. Hence in non-uniform motion magnitude of acceleration is greater than zero . Hence , **non**-uniform motion is accelerated motion.

Velocity is defined as the rate of change of distance of a body with respect to time. Its unit in SI is **km/s**.

The **movement of the body or object or a particle**, that is following a circular path is called a circular motion. Now, the motion of a body or object or a particle moving with constant speed along a circular path is called Uniform Circular Motion.

Translation: **If an object’s speed (velocity) is increasing at a constant rate** then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn’t have uniform acceleration. uniform acceleration.

Uniform circular motion is motion in a circle at constant speed. Centripetal acceleration →aC a → C is the acceleration a particle must have to follow a circular path. Centripetal acceleration **always points toward the center of rotation and has magnitude aC=v2/r.** **a C = v 2 / r** .

Magnitude of centripetal acceleration is given by, a = ω2r. As **ω = vr ∴a=v2r**.

The type of acceleration that occurs during circular motion is known as **centripetal acceleration**.

The centripetal acceleration value increases at a square rate when an object’s velocity increases. The centripetal acceleration value **decreases** when the circular path radius increases and its direction is forever radial inside to the center of rotation.

The time for one revolution around the circle is referred to as the period and denoted by the symbol T. Thus the average speed of an object in circular motion is given by the expression **2•pi•R / T**. Often times the problem statement provides the rotational frequency in revolutions per minute or revolutions per second.

As the centripetal force acts upon an object moving in a circle at constant speed, **the force always acts inward as the velocity of the object is directed tangent to the circle**. This would mean that the force is always directed perpendicular to the direction that the object is being displaced.

So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes called as centripetal force. so,The direction of acceleration of an object moving in a circular path is **directed towards the centre of the circle**.

In a uniform circular motion, the speed of of the body remains the same along the path. But the velocity of the body changes from one point to another in the path because of the change in direction of its motion. … Therefore, **centripetal acceleration cannot change the magnitude of velocity or speed of circular motion**.

In a circular motion, **the object just moves in a circle**. For example, artificial satellites going around Earth at a constant height. In rotational motion, the object rotates about an axis. For example, Earth rotating on its own axis.

According to Newton’s second law of motion, a net force causes the acceleration of mass according to **Fnet = ma**. For uniform circular motion, the acceleration is centripetal acceleration: a = ac. Therefore, the magnitude of centripetal force, Fc, is F c = m a c F c = m a c .
