GENERAL KNOWLEDGE

Detailed explanation-1: -Gravity causes a vertical acceleration. The ball will drop vertically below its otherwise straight-line, inertial path. Gravity is the downward force upon a projectile that influences its vertical motion and causes the parabolic trajectory that is characteristic of projectiles.

Detailed explanation-2: -In conclusion, projectiles travel with a parabolic trajectory due to the fact that the downward force of gravity accelerates them downward from their otherwise straight-line, gravity-free trajectory.

Detailed explanation-3: -Gravity is the only force acting on a projectile. Choose a coordinate axis that where the x-direction is along the horizontal and the y-direction is vertical.

Detailed explanation-4: -A projectile’s motion is parabolic because it is affected by gravity. Gravity causes the projectile to fall in a curved path, rather than a straight line. The equation for projectile motion takes into account the force of gravity, which is why the path of a projectile is always a parabola.

Detailed explanation-5: -FACTORS AFFECTING PROJECTILE MOTION There are three main factors that affect the trajectory of an object or body in flight: the projection angle, magnitude of projection velocity and height of projection.
