Magnitude of velocity is not constant
Both magnitude and direction of velocity change
Velocity is directed towards the centre of the circle
Magnitude of velocity is constant but direction changes
Shown here are the velocities and acceleration vectors for a man in several different types of motion. In which case is the man slowing down and turning to the right
When an object is shot from the bottom of a long smooth inclined plane kept at an angle $60^{\circ}$ with horizontal. it can travel a distance $\mathrm{x}_{1}$ along the plane. But when the inclination is decreased to $30^{\circ}$ and the same object the shot with the same velocity, it can travel $x_{2}$ distance. Then $x_{1}: x_{2}$ will be
A particle is moving in a circular path. The acceleration and momentum vectors at an instant of time are $\vec{a}=2 \hat{i}+3 \hat{j} m / s ^2$ and $\overrightarrow{ p }=6 \hat{ i } + 4 \hat{ j } kgm /$ $s$. Then the motion of the particle is
A cylindrical vessel partially filled with water is rotated about its vertical central axis. It’s surface will
A ball of mass $0.1$ kg is suspended by a string. It is displaced through an angle of ${60^o}$ and left. When the ball passes through the mean position, the tension in the string is ........ $N$
