A particle is moving in a circle
Net force acting on the particle must be toward the centre.
The cross product of tangential acceleration and angular velocity will be zero.
Angular acceleration and angular velocity will be in the same direction.
Net force can be towards the centre.
A particle moves with constant angular velocity in a circle. During the motion its
A particle of mass $m$ describes a circle of radius $r$. The centripetal acceleration of the particle is $4/r^2$. What will be the momentum of the particle?
A simple pendulum is oscillating without damping. When the displacement of the bob is less than maximum, its acceleration vector $\vec a$ is correctly shown in
A particle moves with constant angular velocity in circular path of certain radius and is acted upon by a certain centripetal force $F$. If the angular velocity is doubled, keeping radius the same, the new force will be
Consider a circle of radius $42\ cm$. An insect crawls with uniform speed of $1.3\ cm/s$ along the chord $AB$ then along the circular arc $BCD$ to reach point $D$ and then following cord $DA$ to reach finally $A$. Time spend by the insect to crawl from $A$ to $A$ is closest to ......... $\sec$
