Q: The tendency of an object to resist change in static or dynamic condition is called –
  • A. momentum
  • B. force
  • C. velocity
  • D. inertia
Correct Answer: Option D - Inertia – Inertia is the natural tendency of a body to resist any change in its state of rest or uniform motion in a straight line. For example, a book lying on a table will remain there until an external force is applied on it to remove or displace it from that position. Inertia is of three type : (i) inertia of rest, (ii) inertia of motion (ii) inertia of direction.
