In uniform circular motion, the velocity vector and acceleration vector are
Perpendicular to each other
Same direction
Opposite direction
Not related to each other
The angular acceleration of a body, moving along the circumference of a circle, is :
A solid disc rolls clockwise without slipping over a horizontal path with a constant speed $\upsilon $. Then the magnitude of the velocities of points $A, B$ and $C$ (see figure) with respect to a standing
What is uniform circular motion ? By using proper figure, obtain equation of acceleration ${a_c}\, = \,\frac{{{v^2}}}{r}$ for uniform circular motion. Show that its direction is towards centre.
A car is moving with speed $30$ $m/\sec $ on a circular path of radius $500\, m$. Its speed is increasing at the rate of $2m/{\sec ^2},$ What is the acceleration of the car ........ $m/sec^2$
A particle moving with uniform speed in a circular path maintains:
