difference between inelastic and elastic collisions

Elastic and Inelastic Collisions in One and Two Dimensions - A Karate expert strikes a board of mass 0.14 kg and breaks it, with his fist of mass 0.70 kg. He then does the same to a 3.2 kg concrete block. The spring constant 'k' for bending are, 4.1 x 10 4 N/m for the ..

. The potential energy will be reconverted into kinetic energy. The bodies will separate and continue to move along the same straight line, in the same direction, but with different velocities. Applying the law of conservation of momentum, Total momentum before collision = total..

If the two bodies stick together after the collision, the collision is said to be perfectly inelastic. In this type of collision, the loss of kinetic energy is maximum but not complet..

Elastic Collision in Two Dimensions (Oblique Collision) - If the colliding bodies do not move along the same straight line path, then the collision is said to be an oblique collision..

If the colliding bodies do not move along the same straight line path, then the collision is said to be an oblique collision..

Applications of Elasticity - Mechanical properties like strength, stiffness (Rigidity), ductility, malleability and brittleness have to be carefully studied to select a material for a particular job. The metallic parts of machines should not be subjected to stress beyond the elastich..

Different Forms of Energy - Energy can manifest itself in a number of forms. We have already seen that it can be in the form of mechanical energy, which is subdivided into kinetic energy and potential energy. Potential energy can arise due to different causes. For instance, as w..
