Question

After landing the aeroplanes momentum becomes zero. explain how the law of conservation holds here.

Answer 1

Answer:

Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.

Answer 2

Answer:

The law of conservation holds here as the net external force acting on the plane is zero.

Explanation:

• Here the law of conservation of momentum holds good as the net external force acting on the system is zero.
• Airplanes work on the principle of conservation of momentum, which states that if the system's starting momentum is zero, the system's ultimate momentum must also be zero. As a result of the rebound of the gases of the fuel ejected in the backward direction, the airplane goes forward.
