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

Question # 1

What is the change in total energy during elastic or inelastic collisions?

  • Ans 1: The total energy of the system remains conserved during both type of collisions. But in an inelastic collision, some of the kinetic energy is lost .

Question # 1

Name the quantities which can be calculated from velocity-time graph and these can be calculated ?

  • Ans 1: Distance moved by the body and its acceleration can be calculated by the velocity-time graph.
    Area under the velocity time graph line is equal to the distance covered by the body. Slope of the tangent at any point gives the instantaneous acceleration at that point.

Question # 1

State law of inertia?

  • Ans 1: Newton's 1stlaw of motion is called law of inertia
    It states that a body at rest will remain at rest , and a body moving with uniform velocity will continue to do so, unless acted upon by some unbalanced external force.
