A rocket is launched and travels far from the Earth. The effect of the Earth's gravity on the motion
of the rocket is insignificant. As the rocket accelerates, its momentum increases.
Explain how the principle of the conservation of momentum applies to the accelerating rocket and
the exhaust gases.

when it gains or loses electrons

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
