Q1 When a bus suddenly takes a turn, the passengers are thrown outwards because of

  • (a) Inertia of direction 
  • (b) Inertia of motion
  • (c) Inertia of rest 
  • (d) Acceleration of motion

  • (a) Inertia of direction 

Q2 Two bodies of equal mass, one in motion and another is at rest, then which is correct for these bodies

  • (a) both possess no inertia
  • (b) both possess different inertia
  • (c) both have same inertia
  • (d) can’t say anything

  • (c) both have same inertia, because inertia is a factor of mass only and does not depend upon velocity

  • (a) Increase its speed 
  • (b) Decrease the momentum
  • (c) Change the direction 
  • (d) Keep it moving with uniform velocity

  • (d) Keep it moving with uniform velocity

  • (a) Force 
  • (b) Displacement
  • (c) Speed 
  • (d) Velocity

  • (a) Force

  • b) Law of Inertia
  • c) Law of conservation of energy
  • d) None of these

  • b) Law of Inertia
