elastic vs inelastic 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 ..

A collision is said to be an elastic collision if both the kinetic energy and momentum are conserved in the collision. During collision, the bodies are deformed. However, they regain their original shape completely if the collision is ..

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..

It is that elastic collision in which the colliding bodies move along the same straight line before and after the collision. Consider two bodies A and B of masses m 1 and m 2 respectively, moving along the same straight line, in the same direction. Let be their respect..

>) and g the acceleration due to gravity (~10m/s 2 ). The pressure at the base should be less than the elastic limit of the Earth's supporting material (3 x 10 8 N/m 2 ) The stress vs strain for elastomers is a curve like this While using a material, it is ensured that the worki..

A body of mass m 1 is moving with a velocity along X-axis. Let it suffer elastic collision with a stationary body of mass m 2 . The distance b, between the initial line of motion and a line parallel to it through the centre of the target body is called the impact parameter. T..

>Law of conservation of energy states that the total energy of an isolated system cannot change. A collision is said to take place when either two bodies physically collide against each other or when the path of one body is changed by the influence of the other body. A collision..
