$\huge{\red{\mathfrak{ANSWER:-}}}$

Projectile motion occurs when objects are fired at some initial velocity or dropped and move under the influence of gravity. One of the most important things to remember about projectile motion is that the effect of gravity is independent on the horizontal motionof the object.

Answer 2

Answer:

Due to gravitational pull of earth.

Explanation:

From first law of Newton, A body with no external force moves in a straight line either with a constant velocity or with zero velocity..However in Earth , Due to fact that earth applies force towards its centre to everybody, Body instead of travelling in straight line with angle from ground, it moves in a parabolic path,due to acceleration due to gravity .
