When a particle moves in a uniform circular motion. It has

ARadial velocity and radial acceleration

BTangential velocity and radial acceleration

CTangential velocity and tangential acceleration

DRadial velocity and tangential acceleration

Solution

An object moving in a circle is accelerating. Accelerating objects are objects which are changing their velocity – either the speed (i.e., magnitude of the velocity vector) or the direction. An object undergoing uniform circular motion is moving with a constant speed.

A racing car is travelling along a track at a constant speed of $40\ m/s$. A $T.V.$ camera men is recording the event from a distance of $30\ m$ directly away from the track as shown in figure. In order to keep the car under view in the position shown, the angular speed with which the camera should be rotated, is …….. $rad/sec$.

A car is going round a circle of radius $R_1$ with constant speed. Another car is going round a circle of radius $R_2$ with constant speed. If both of them take same time to complete the circles, the ratio of their angular speeds and linear speeds will be ………

An insect trapped in a circular groove of radius $12 \;cm$ moves along the groove steadily and completes $7$ revolutions in $100\; s$.
$(a)$ What is the angular speed, and the linear speed of the motion?
$(b)$ Is the acceleration vector a constant vector ? What is its magnitude ?

Three point particles $P, Q, R$ move in circle of radius $‘r’$ with different but constant speeds. They start moving at $t = 0$ from their initial positions as shown in the figure. The angular velocities (in rad/ sec) of $P, Q$ and $R$ are $5\pi , 2\pi$ & $3\pi$ respectively, in the same sense. the number of times $P$ and $Q$ meet in that time interval is:
