A particle performs uniform circular motion

This action cannot be undone. This will permanently delete All Practiced Questions. A particle performs uniform circular motion with an angular momentum L. If the frequency of the particle motion is double, the angular momentum becomes.

The turning momentum of the particle about the axis of rotation is called the angular momentum of the particle. Mathematically angular momentum can be written as -. The energy, which a body has by virtue of its rotational motion, is called rotational kinetic energy. A body rotating about a fixed axis possesses kinetic energy because its constituent particles are in motion, even though the body as a whole remains in place. Mathematically rotational kinetic energy can be written as —. Get Started.

Exam Info. Angular momentum also depends on the rotational velocity and the rotational inertia.

A particle performs uniform circular motion with an angular momentum. If the frequency of particle's motion is double and its kinetic energy is halved then determine value of angular momentum. Dont't have an account? Register Now. Colleges Colleges Accepting B.

Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. Other examples are the second, minute, and hour hands of a watch. It is remarkable that points on these rotating objects are actually accelerating, although the rotation rate is a constant. To see this, we must analyze the motion in terms of vectors. In one-dimensional kinematics, objects with a constant speed have zero acceleration. However, in two- and three-dimensional kinematics, even if the speed is a constant, a particle can have acceleration if it moves along a curved trajectory such as a circle. Furthermore, since. From these facts we can make the assertion. Summarizing, a particle moving in a circle at a constant speed has an acceleration with magnitude.
