Question

DATE:
Describe elastic collision
and discuss it for two
bodies in one
dimension.
Calculate the velouties
of
bodies after collision
Discuss special causes also.​

Answer 1

Answer:

We start with the elastic collision of two objects moving along the same line—a one-dimensional problem. An elastic collision is one that also conserves internal kinetic energy. Internal kinetic energy is the sum of the kinetic energies of the objects in the system. Figure 1 illustrates an elastic collision in which internal kinetic energy and momentum are conserved.

Truly elastic collisions can only be achieved with subatomic particles, such as electrons striking nuclei. Macroscopic collisions can be very nearly, but not quite, elastic—some kinetic energy is always converted into other forms of energy such as heat transfer due to friction and sound. One macroscopic collision that is nearly elastic is that of two steel blocks on ice. Another nearly elastic collision is that between two carts with spring bumpers on an air track. Icy surfaces and air tracks are nearly frictionless, more readily allowing nearly elastic collisions on them.

Answer 2

Answer:

Define elastic collision and discuss it for two bodies in one dimension. Calculate the velocities of bodies after collision. What percentage of kinetic energy of a moving particle is transferred to a stationery particle when moving particle skrikes with a stationery particle of mass 9 times in mass.
