# What is the direction of acceleration in circular uniform motion?

It is towards the centre of the circle.

Towards the center of the 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.

### 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.

### 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.

### 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.

### 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 does an object in uniform circular motion exhibits acceleration when its speed is constant?

Because "acceleration" doesn't mean 'speeding up'. It means any change in the speed or direction of motion. The only motion that's not accelerated is motion at a constant speed in a straight line. If the speed is increasing, or the speed is decreasing, or the direction is changing, that's 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 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 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 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.

### 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.

### For a particle in circular motion the resultant acceleration is?

Since no values are given, the answer must be a general one. A particle in circular motion undergoes centripetal acceleration. Inertial motion is straight line motion. Any change in motion (including direction) requires positive or negative acceleration. In order to move along a circular (or any curved) path, a particle's direction of motion is in a constant state of diversion from straight line inertial motion, so it moves under a contant state of acceleration.

### Uniform and non-uniform motion?

if a body performs motion with constant speed along a circular path,its motion is called uniform circular motion. here,note that speed remains constant , not velocity. direction of velocity of a body in uniform circular motion, is different at each point on the circular path. consider a body performing uniform circular motion along the circle of radius'r' in anticlock wise direction. when this object is on points a,b,c,d and e, directions of its velocity are…

### What is the uniform circular motion?

Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Since the direction of the velocity vector is the same as the direction of the object's motion, the velocity vector is directed tangent to the circle as well. Hope this helps!!

### How can free fall motion and circular motion both be classified as acceleration?

Answer #1: Free fall is motion due to gravity. centripetal force causes the acceleration in a circular motion. =========================== Answer #2: "Acceleration" means a change in either the speed or the direction of motion. (Or both, of course.) Maintaining a steady 30 miles per hour as you round a curve is acceleration. In the case of free fall, the speed is constantly increasing. In the case of circular moltion, the direction is constantly changing, and…
