the given vector


◉ Resolution. Answer: the process of determining the components
of a vector


◉ Projectile. Answer: any object that moves through the air, space,
acted on only by gravity.


◉ Momentum. Answer: the mass of an object multiplied by its
velocity


◉ Impulse. Answer: the quantity force times time interval.


◉ The law of conservation of momentum. Answer: in the absence of
an external force, the momentum of a system remains unchanged.

, ◉ Elastic Collision. Answer: when objects collide without being
permanently deformed and without generating heat. (Bouncing
occurs)
