This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.

What will be acceleration of a car moving in a circular motion with constant speed.?

If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.


How when something travels in a circle its always accelerating?

When an object travels in a circle, it is constantly changing direction, which means its velocity is also changing, even if its speed remains constant. Acceleration is defined as the rate of change of velocity, and since velocity includes both speed and direction, any change in direction constitutes acceleration. This continuous change in direction toward the center of the circle is what is known as centripetal acceleration. Therefore, an object in circular motion is always accelerating due to this constant change in direction.


Acceleration is an increase of speed during a given interval of time?

No. It is the change in velocity (not speed) during a given interval of time. It can be an increase or a decrease although a decrease is also called a deceleration.The distinction between velocity and speed can best be illustrated by an object going round in a circle at a constant speed. It is changing direction all the time so that its velocity is constantly changing. It is constantly accelerating even though it is travelling at constant speed.


A car moves in uniform circular motion around a curve in the road What is the direction of the car's acceleration?

If the speed is constant, the acceleration is toward the center of the circle.


If a particle moves in circle with constant speed its angular momentum about the center of circle?

The angular momentum is a constant.

What remain constant in uniform circular motion?

In uniform circular motion, the speed of the object remains constant as it moves around the circle. However, the velocity of the object changes because the direction of the velocity vector is constantly changing. The centripetal acceleration remains constant in magnitude and always points towards the center of the circle.


Is the velocity constant for an object in uniform circular?

Answer: No, the speed is constant, but the velocity changes, since the direction changes. Please be sure you understand the difference between "speed" and "velocity", as used in physics. Speed is scalar which has only magnitude but not direction Whereas velocity is having both. So is a vector quantitiy


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 components are constant.


Which physical quantity changes continuously during uniform circular motion?

The direction of velocity changes continuously during uniform circular motion. The magnitude of velocity remains constant, but its direction is constantly changing as the object moves around the circle.


Can uniform angular velocity has acceleration?

No, uniform angular velocity implies that an object is moving in a circle at a constant rate. Since acceleration is defined as any change in velocity (either speed or direction), if the angular velocity is constant, there is no acceleration present.


Can a body have constant velocity when it has constant speed?

Of course. In fact, in order to have constant velocity, it must have constant speed.What you really want to know: Can a body have changing velocity when it has constant speed ?The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).


Why object moves in a circle have a constant speed and velocity?

An object moving in a circle at a constant speed has a changing velocity because velocity is a vector quantity that includes both speed and direction. In circular motion, the object is constantly changing direction, so its velocity is changing even though its speed remains constant.


If a car drove a around in a circle would that be constant velocity?

No. Velocity is a 'vector', which means it's a measurement that has both magnitude and direction. The magnitude is what we usually call the 'speed'. For an object moving in a circle, it could have constant speed ... the velocity could have constant magnitude ... but there's no way the whole velocity vector could be constant, because the direction is always changing. Constant velocity is very easy to recognize ... the object is moving at a steady speed, in a straight line.


When an object does circular motion what is constant?

When an object is performing circular motion, the speed of the object remains constant, while the velocity is constantly changing due to the direction changing. The centripetal force required to keep the object moving in a circle is also constant.


Can uniform velocity appear in circular motion?

No.. this is impossible. Velocity must have a constant direction and speed to remain constant, it may have a constant speed, but the direction in a circle constantly changes. If it suddenly were to have constant direction, then the motion would go off on a tangent.. making it linear motion, not circular. In circular motion, velocity constantly changes. Always.


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.
