what is collicion ?how many types of collision explain elastic collision mathematically write its special cases also
Answers
Explanation:
a crash; an occasion when things or people collide
भिड़ंत; वस्तुओं या व्यक्तियों के बीच टक्कर
Answer:
Collision means two objects coming into contact with each other for a very short period. In other words, collision is a reciprocative interaction between two masses for a very short interval wherein the momentum and energy of the colliding masses changes.
Explanation:
Generally, the law of conservation of momentum holds true in the collision of two masses but there may be some collisions in which Kinetic Energy is not conserved. Depending on the energy conservation, conservation may be of two types:
Elastic Collision: In the elastic collision total momentum, the total energy and the total kinetic energy are conserved. However, the total mechanical energy is not converted into any other energy form as the forces involved in the short interaction are conserved in nature. Consider from the above graph two masses, m1 and m2 moving with speed u1 and u2. The speed after the collision of these masses is v1 and v2 . The law of conservation of momentum will give:
m1u1 + m2u2 = m1v1 + m2v2
