During uniform circular motion of object out of (i) magnitude of velocity (ii) magnitude of force (iii) acceleration (iv) momentum vector is not constant.

Which out of (i) value of velocity, (ii) value of acceleration, (iii) value of force, (iv) the momentum vector of the body is not constant during uniform circular motion ?

In uniform circular motion (i) only the value of velocity is constant. (ii) velocity vector is constant. (iii) direction of velocity is constant. Select the correct one.

An object is moving in x-y plane its velocity and acceleration at t=0 are represented in figure. The ratio of magnitude of velocity to magnitude of component of acceleration along velocity at t=0 :-

For a body in circular motion with a constant angular velocity, the magnitude of the average acceleration over a period of half a revolution is … times the magnitude of its instantaneous acceleration.

A particle moves in such a way that its position vector at any time t is vec(r)=that(i)+1/2 t^(2)hat(j)+that(k) . Find as a function of time: (i) The velocity ((dvec(r))/(dt)) (ii) The speed (|(dvec(r))/(dt)|) (iii) The acceleration ((dvec(v))/(dt)) (iv) The magnitude of the acceleration (v) The magnitude of the component of acceleration along velocity (called tangential acceleration) (v) The magnitude of the component of acceleration perpendicular to velocity (called normal acceleration).

A particle is performing circular motion of radius 1 m. Its speed is v=(2t^(2)) m//s . What will be magnitude of its acceleration at t=1s .

An object performing uniform circular motion performs accelerated motion.

A particle executes linear simple harmonic motion with an amplitude of 3 cm. When the particle is at 2 cm from the mean position, the magnitude of its velocity is equal to that of its acceleration. Then its time period in second is…….

For circular motion if angular velocity is constant then Angular momentum will also constant.
