A particle performs uniform circular motion

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. SSC Exams. Banking Exams. Teaching Exams. Civil Services Exam. Railways Exams. Engineering Recruitment Exams.

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.

The learning objectives in this section will help your students master the following standards:. In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Circular and Rotational Motion, as well as the following standards:. Ask students to give examples of circular motion. Review linear acceleration. In the previous section, we defined circular motion. The simplest case of circular motion is uniform circular motion , where an object travels a circular path at a constant speed. Note that, unlike speed, the linear velocity of an object in circular motion is constantly changing because it is always changing direction. We know from kinematics that acceleration is a change in velocity , either in magnitude or in direction or both.
