A simple pendulum of length has mass and it oscillates freely with amplitude . At the extreme position, its potential energy is ( = acceleration due to gravity)
For a simple pendulum, a graph is plotted between its kinetic energy (K.E.) and potential energy (P.E.) against its displacement d. which one of the following represents these correctly? (graphs are schematic and not drawn to scale)
A mass attached to a horizontal spring executes of amplitude . When the mass passes through its mean position, then a smaller mass is placed over it and both of them move together with amplitude . The ratio of is
A body of mass moving with velocity explodes into two equal parts. If one part comes to rest and the other part moves with velocity ; what would be the value of ?
A particle is executing simple harmonic motion with a time period . At time , it is at its position of equilibrium. The kinetic energy - time graph of the particle will look like:
