Yes as a body moves along a circular path with uniform speed, its direction is ever changing. Hence the velocity is changing. So acceleration must be present. If acceleration vector is in the direction of the velocity then definitely its magnitude would change and so we cannot say the motion to be uniform. So the acceleration has to be perpendicular to the velocity vector, so it has to be along the radius. Hence the acceleration is named as radial acceleration. The force thus produced is known as centripetal force ie centre seeking force.

An object moving in a circle of radius r with constant speed v is accelerating. ... The acceleration vector must therefore be perpendicular to the velocity vector ...

An object moving in a circle of radius r with constant speed v is accelerating. The direction of its velocity vector is changing all the time, but the magnitude of the velocity vector stays constant. The acceleration vector cannot have a component in the direction of the velocity vector, since such a component would cause a change in speed. The acceleration vector must therefore be perpendicular to the velocity vector at any point on the circle. This acceleration is called radial acceleration or centripetal acceleration, and it points towards the center of the circle. The magnitude of the centripetal acceleration vector is ac = v2/r. (We skip the derivation of this expression.)

## FAQs

### For An Object To Move In A Uniform Circular Motion, It Must Move With Constant? ›

The component of any net force that causes circular motion is called a centripetal force. When the net force is equal to the centripetal force, and its magnitude is constant, uniform circular motion results.

**Does an object moving in uniform circular motion have a constant? ›**

An object undergoing uniform circular motion is moving with a **constant speed**. Nonetheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards.

**What is required to keep an object moving in uniform circular motion? ›**

Circular motion requires **a net inward or "centripetal" force**. Without a net centripetal force, an object cannot travel in circular motion. In fact, if the forces are balanced, then an object in motion continues in motion in a straight line at constant speed.

**What is the condition for an object to move in circular motion? ›**

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 referred to as the centripetal force requirement. The word centripetal (not to be confused with the F-word centrifugal) means center seeking.

**What is constant in uniform circular? ›**

The **speed and the angular velocity** remain constant in case of uniform circular motion. The magnitude of centripetal acceleration also remains constant.

**Which is always constant in a uniform motion? ›**

For uniform motion, **the speed of the moving body** is always constant.

**What is correct for uniform circular motion? ›**

In a uniform circular motion, **the magnitude of the velocity of the body remains constant**. However, the direction of the body keeps changing. Hence, there is a non-zero velocity which keeps changing due to change in direction.

**Which are the two requirements absolutely necessary for circular motion? ›**

They are the **centripetal force and centrifugal force**. These two forces form the foundation of circular motion.

**What other factors can affect circular motion? ›**

**Three factors which affect the centripetal force are:**

- mass of the object;
- its speed;
- the radius of the circle.

**What happens when an object moves in a circular path? ›**

When an object moves in a circular path **it changes into direction and velocity at every point**. The force that causes this velocity or acceleration is called centripetal force. It always acts in the inwards direction i.e, towards the center.
