Energy Transformation for a Pendulum
Because there are no external forces doing work and the total mechanical energy of the pendulum bob is conserved. The conservation of mechanical energy is described in the animation below. Assume the KE and PE bars of the bar chart and their sum is a constant value.
It consists of two semis circular plates. One is of quartz and other is glass plate joined together along the diameter. The quartz semi circular plate is a half wave plate whose

HEAD-ON COLLISION: "If the centers of the colliding bodies stay moving along the similar straight line, the collision is said to be head-on collision".
An alternating voltage given by v=100sin240t volts is applied across a coil of resistance 32 and inductance 100mH. Verify (a) the circuit impedance, (b) the current flowing,
Ball bearings Place some marbles in the lid of a tin on the floor. Put single foot on the marbles and notice how simply you can spin round.
