Show that there is a loss of kinetic energy during one dimensional inelastic collision. How will you account for this loss of energy ?

Show that the loss of kinetic energy occurs in an inelastic collision . How will you justify this loss of energy ?

The loss of kinetic energy during the above proces is

Is whol of the kinetic energy lost in any perfectly inelastic collision?

How do we control AC without much loss of energy?

Two discs of moments of inertia I_(1) and I_(2) about their respective axes (normal to the disc and passing through the centre), and rotating with angular speed omega_(1) and omega_(2) are brought into contact face to face with their axes of rotation coincident (i) What is the angular speed of the two-disc system ? (ii) Show that the kinetic energy of the combined system is less than the sum of the initial kinetic energies of the two discs. How do you account for this loss in energy ? Take omega_(1) ne omega_(2) .

A ball at rest is dropped from a height of 12m. It loses 25% of its kinetic energy in striking the ground, find the height to which it bounces. How do you account for the loss in kinetic energy ?

In what is the loss in kinetic energy of the system due to impact ?
