On this day of numerical glory, get to know pi in an unusual way: using the elastic collision of two different masses and a wall.

If it's a real Newton's cradle with perfectly elastic collisions, then the kinetic energy of the launched ball should be equal to the total kinetic energy of all the stuff moving after the impact.

• The relation between velocity of approach and the velocity of separation for perfectly elastic collision, this approach is used to solve numerical like: a) How much the energy will be ...

Illustrates how kinetic energy is transferred from one body to another through elastic collisions. Explains formulas for calculating the exchange of energy. Defines concepts concerning stored ...

Inelastic demand is a term used to describe the unchanging quantity of a good or service when its price changes.

A super-elastic collision is one that results in an increase of kinetic energy in the colliding system. A probable occurrence of such a collision is shown in the huge, magnetized plasmas of two ...
