Curvilinear Motion & Kinematics

Projectile Motion :-

Definition & Concept:-

A body projected into space and is no longer provided with any fuel is called projectile and motion of the body is said to be projectile motion.

A projectile can be thrown into all possible directions into the 3D space, which is categorized into three parts,

1. along vertical direction.

2. along horizontal direction.

along any direction making an angle of θ with horizontal.

When the projectile is thrown towards the gravitational force of earth , acceleration of the object is equal the value of acceleration due to gravity. When it is thrown opposite to force of gravity, acceleration of the object is negative of the value of acceleration due to gravity.

When the projectile is thrown in any direction making an angle θ with the horizontal, its motion can be consider as the resultant of horizontal and vertical motion.
