What is the direction of acceleretion of a body in circular motion?
-- The acceleration is directed from the body to the center of the circle. -- The velocity is tangent to the circle at the place where the body is. That direction is also perpendicular to the acceleration at that moment.
What is angular velocity and radial velocity?
Angular velocity is the rate of change of angle of a body, i.e.omega =v / r =(2*pi*r)/ r*t=(2*pi)/ Twhere T is the time period of whatever is rotating and r is the radius of the circle.So if a circular disc is spinning at 1 m/s then the angular velocity of it is 2*pi radians/ secondRadial velocity is the velocity in m/s at the radius of the circle i.e.radial velocity v =omega*r=(2*pi*r)/ T(equivalent to speed =distance/ time where in this case distance is the circumference of the circle and time is the time period of one rotation)----------------------------------------------------------------------------------------------------Angular velocity ω, is the rate of change of angular displacement dφ/dt. Itspecifies the angular speed (rotational speed) of an object and the axis about which the object is rotating.ω =2πf=2π/T [=]rad/swhere f is the rotation frequency (rev/s) and T the time it takes to make arevolution (s/rev).Tangential velocity v. When an object rotates around in a circle with radius r, itslinear velocity tangent to the circle is the tangent velocity v.v =ωr[=]m/sRadial velocity vr, is the component of the velocity of an object away ortowardthe origin or point of observation.

What is an object always changing if it is moving in a circle?
If an object is moving in a circle (like a teather ball or a planet in orbit, although orbit is not a perfect circle), then its velocity is always changing (remember that velocity is speed AND direction, and since the direction is changing, the velocity is changing). It's position is also always changing as a result of having a velocity.
How many times centripetal force will increase if the angular speed of a body moving with uniform speed moving in a circle is increases?
Centripetal acceleration, and therefore centripetal force, is proportional to the square of the angular velocity. For example, if you increase the angular velocity by a factor of 10, the centripetal force will be increased by a factor of 100.
What is the difference betweentangential velocity or angular velocity?
angular velocity s the rotational analague of linear velocity...direction of linear velocity s along tangent to the circle while that of angulr velocity s along the axis of rotation.the direction of angular v can be find by right hand rule which state that if the axis of rotation s held n right hand with fingers curled round the direction of rotation then the thumb will mark the direction of angular velocity.... the magnitude of angular velocity that s the angular speed is represented by the length of the line along the axis of rotation...its units are rad/sec,degrees/sec or revolution/sec while that of linear velocity s m/sec...
How do you use angular in a sentence?
A triangle is an angular shape. A circle is not angular.
How do you increase the angular velocity of a rotating object?
Angular velocity just means how fast it's rotating. If youaa want more angular velocity, just rotate it faster or decrease the radius (move it closer to the center of rotation). Just like force = rate of change of momentum, you have torque= rate of change of angular moment Or We can increase the angular velocity of a rotating particle by applying a tangential force(i.e. accelaration) on the particle. Since the velocity of the particle is tangential with the circle along which it is moving, the tangential accelaration will not change the diriction of the velocity(as angle is 0),but will cause a change in magnitude. Thus angular velocity will increase.

' uniform motion in a circle in which speed is constant but velocity is changing'?
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.
How circular velocity is constant in circular motion?
Velocity constantly changes as so does the direction around a circle...

If velocity dSdt and speed dSdt then what happened when a body move in a complete circle were dS0 then velocity?
Velocity is a vector, meaning it has a direction, like east, north, up. Speed isa magnitude without direction, 60 miles per hour is a speed; 60 miles per hour north is a velocity. When a care is going 60 mph in a circle the speed is constant but the velocity changes as the direction changes. The magnitude of the velocity is the same but the direction changes thus the velocity changes. Velocity changes if either the speed/magnitude or the direction change.
When can an object a constant speed but not a constant velocity?
If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.
