    The principle of conservation of linear momentum can be strictly applied during a collision between two particles provided the time of impact is

  • Moderately small
  • Extremely large
  • Extremely small
  • Depends on a particular case

  • 2. 
    In an elastic collision of two particles the following is conserved

  • Kinetic energy of each particle
  • Total kinetic energy of both the particles
  • Momentum of each particle

  • 3.

  • Be at rest
  • Move with the same velocity in the same direction
  • Move with the same velocity in opposite directions

  • 4. 
    A lead ball strikes a wall and falls down, a tennis ball having the same mass and velocity strikes the wall and bounces back. Check the correct statement.

  • The momentum of the lead ball is greater than that of the tennis ball
  • Both suffer an equal change in momentum

  • 5. 
    When two bodies collide elastically, then
