2.3 Motion in Two Dimensions
The motion of an object projected at an angle to the horizontal level and subjected to acceleration due
to the gravity of the Earth alone, is called projectile motion. The air resistance is assumed to be absent
and the horizontal level is considered to be a plane and the curvature of Earth's surface is neglected.
Locally, the projectile motion can be analyzed as a two component motion : Horizontal component
with uniform horizontal velocity and vertical component with uniform acceleration due to gravity of Earth.
