Question # 1

Define Collision ? Discuss the type of collision?Give example in each case?

  • Ans 1: Collision:When two or more than two bodies come so closer to each other that there exists some type of interaction between them in the presence or absence of external forces then such type of interaction is known as collision.
    Type of Collision:There are two type of collision, which are given below.
    Elastic Collision:The Collision in which the momentum and kinetic energy both are conserved is known as elastic collision.
    Examples:
    1. collision of steel balls,
    2. Collision of atoms,
    3. Collision of molecules.
    Inelastic Collision:The Collision in which the momentum is conserved but K.E is not conserved, is known as Inelastic collision. "
    In such type of collision, same type of the K.E is converted into internal energy, sound energy and the work needed to permanently deform the object involed, such as cars ina car crash.
    Example:
    1. Collision between two vehicles
    2. Collision between two mud balls
