A particle performs uniform circular motion

If it's angular frequency is doubleded and the rotational kinetic energy is halved, then what will be the new angular momentum? Find its acceleration and the distance it covers in that time.

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.

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. In figure a , a meter stick, half of which is wood and the other half steel is pivoted at the wooden end at O and a force F is applied to the steel end a. In figure b the stick is pivoted at the steel eid at O' and the same force F is applied at the wooden end at a' The angular acceleration. A 20 kg solid disc rolls on a horizontal surface at the rate of 4 m s - 1. Its total kinetic energy is. From a uniform square plate of side a and mass m, a square portion DEFG of side a 2 is removed. Then, the moment of inertia of the remaining portion about the axis AB is:.

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.
