Description : A jet engine works, on the principle of conservation of - (1) linear momentum (2) angular momentum (3) energy (4) mass
Last Answer : (1) linear momentum Explanation: Linear momentum is a vector quantity defined as the product of an object's mass, m, and its velocity, v. Linear momentum is denoted by the letter p and is called ... for short: Note that a body's momentum is always in the same direction as its velocity vector.
