# Why tangential acceleration is not produced in uniform circular motion?

Because there is no tangential force acting on the object

in uniform circular motion.

The proof that there is no tangential component of acceleration is

the fact that the tangential component of velocity is constant.

### What is the acceleration when a particle move along circular path with constant speed?

When a particle is moving in uniform circular motion , its speed is constant . Velocity of particle changes from point to point due to change of direction of particle in uniform circular motion. This change in velocity vector leads to an acceleration which acts towards the center of circular path. The acceleration is known as Centripetal acceleration.

### In order for an object to move in uniform circular motion it must be accelerating?

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 the statement 'a body moving with uniform speed along a circular path is subjected to uniform acceleration' true or false justify?

This statement is true. This type of movement is called Uniform Circular Motion. For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.

### What is uniform circular motion?

Uniform circular motion describes motion in which an object moves with constant speed along a circular path. In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of…

### What is the difference between uniform linear motion an uniform circular motion?

linear is which is on a straight path and circular motion is which has a curved path. *In a uniform linear motion,the velocity is constant and the acceleration is zero.So,uniform linear motion is an unaccelerated motion. *In uniform circular motion the velocity can be variable although the speed is uniform.So,it is an accelerated motion.

### Why is uniform circular motion an example of uniform acceleration?

With no acceleration a body moves at constant speed in a straight line. However to travel a circular path you have to apply a force to bend the path of the object form a straight line into a circle. The application of this force is an acceleration. Note too that because the path is circular, the SAME force is required at all points of the circle this makes the acceleration UNIFORM. If you do not…

### Is uniform circular motion and circular motion is the same?

no, in uniform circular motion the magnitude of your velocity, and therefore your acceleration is constant. in general this does not need to be true. consider this simple experiment, in a children's playground, go to a roundabout. stand on the roundabout and kick once, then wait for your motion to completely stop before kicking again. your motion is still circular, but neither velocity or acceleration is constant.

### What is uniform in uniform circular motion?

The speed of the object in motion, the radius of the curve in which it moves, the force acting on it to keep it moving in a circle, its angular velocity, and its centripetal acceleration, are all constant. Notice that its linear velocity is not constant, because the direction of its motion is always changing. Although I guess you'd have to say that its velocity is constant in polar coordinates, because the radial and tangential…

### Which type of acceleration occurs in circular motion?

An object in circular motion experiences continuous change in its direction of motion, and may or may not experience changes in its speed. Either change constitutes acceleration. The force that keeps an object in circular motion is often directed toward the center of the circle. It's then known as "centripetal" force, and produces centripetal acceleration.

### Why is uniform circular motion considered acceleration?

Acceleration is defined as the change in velocity divided by the time or a = (vf - vi)/t Velocity measures the speed and the direction of an object. In uniform circular motion, the object has the same speed but it is always changing direction and so, by the definition of acceleration, the object is considered accelerating. If this acceleration doesn't exist, the object would move in a straight line according to Newton's laws of motion.

### What is the correct name for circular motion?

If the motion is truly in the form of a circle, the phrase uniform circular motion describes it appropriately. This means that the object is in a constant state of motion about a fixed point at a constant distance from that point. Circular motion can be considered an acceleration, because an acceleration describes any change in velocity or direction. Since circular motion involves constant change in direction, the object exhibits constant acceleration.

### How can the acceleration be different from zero in a circular uniform movement?

Ah hah! You're one of those individuals who thinks that "acceleration" means "speeding up". Admit it. It doesn't. 'Acceleration' is any change in the speed or direction of motion. In circular motion, the direction is constantly changing. So, although the speed is constant, that's accelerated motion.
