The motion of a body along the circumference of a circle with constant speed is called uniform circular motion. In U.C.M, direction of velocity is along the tangent drawn to the position of particle […]

Write down the main characteristics of angular acceleration.
Characteristics of angular acceleration: Angular acceleration is positive if angular velocity increases with time. Angular acceleration is negative if angular velocity decreases with time. Angular acceleration is an axial vector. In uniform circular motion, angular velocity is constant, so angular […]
Are the following motions same or different?
i. Motion of tip of second hand of a clock.? ii. Motion of entire second hand of a clock? Both the motions are different. The tip of the second hand of a clock performs uniform circular motion while the entire […]
State right hand thumb rule to find the direction of angular displacement.
Right hand thumb rule: Imagine the axis of rotation to be held in right hand with the fingers curled around it and thumb out-stretched. If the curled fingers give the direction of motion of a particle performing circular motion then […]
Define Centripetal and centrifugal forces
Centrifugal Force Meaning – Centrifugal force (Latin for “center fleeing”) describes the tendency of an object following a curved path to fly outwards, away from the center of the curve. It’s not really a force; it results from inertia — […]
Define Circulation Motion and Angular Displacement?
Circulation motion: In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and […]
