Jet airplanes work on the principle of conservation of momentum.
Newton is the SI unit of force.
Acceleration remains same since a = Now if force is doubled i.e. 2F and mass is doubled i.e. 2m Then acceleration a = =
Force acting on a body is directly proportional to the acceleration produced in the body. F ∝ a
A newton force is defined as that force which when acting on a body of mass of 1 kg produces an acceleration of 1 m/s2 in it.
The SI unit of force is newton(N).
The rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts.
Force corresponds to the rate of change of momentum.
