GENERAL KNOWLEDGE

Detailed explanation-1: -A particle moves along a curved path under constant acceleration when thrown obliquely near the Earth’s surface. This curved path is always directed towards the centre of the Earth. The path of such a particle is called the projectile’s trajectory, and the motion is called projectile motion.

Detailed explanation-2: -Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity. The object is called a projectile, and its path is called its trajectory.

Detailed explanation-3: -The trajectory of a projectile is a parabola. Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path. The path that the object follows is called its trajectory.

Detailed explanation-4: -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.
