PROBLEMS (HARD) 1) A particle is suspended by a string of length ‘l’. This is projected with such a velocity v along the horizontal such that after the string becomes slack it flies...

PROBLEMS (MODERATE) 1) A hemispherical bowl of radius R = 0.1m is rotating about its own axis (which is vertical), with an angular velocity w. A particle of mass 10-2Kg on the frictionless inner...

PROBLEMS (EASY) 1) Force acting on a particle varies with x as shown in figure (33) .Calculate the work done by the force as the particle moves from x = 0 to x = 6m. Fig (33) Solution: The...

Banking of Roads: When vehicle go through turnings, they travel along a nearly circular arc. There must be some force to produce the required centripetal acceleration. Centripetal force is provided...

Derivation: Motion in a vertical circle:        A particle of mass m is attached to inextensible light string of length l and it is imparted a velocity u in...

CIRCULAR MOTION: Uniform Circular motion:  Angular velocity w is constant throughout the motion. The magnitude of velocity also remains constant. Non-Uniform Circular motion:  Angular...

WORK ENERGY THEOREM: Work Energy theorem states that, the net change in Kinetic Energy of a particle (system) is equivalent to the sum of work done by all types of external forces be it conservative...
