Let us Begin by Understanding the basics of the Law of independence: 

– Law of independence

• Motion in perpendicular directions is mutually independent.

• Motion in a plane is resolved into two parts.

Now that we have established a basic understanding of the law of independence: 

Important Definitions:

• A motion is curvilinear when initial velocity and acceleration are non-collinear.

• Acceleration has two components also: 

•  Tangential acceleration: Responsible for changes in speed

• Normal/Radial/Centripetal Acceleration: 

Responsible for changing the direction of velocity.

– Projectile Motion(Types)

• Object projected non-vertically are projectiles.

• It follows a Parabolic Path.
• It is motion under gravity (uniformly accelerated motion)

Types:

• Horizontal Projection
• Oblique Projection
• General Projection

– Horizontal Projection

Combination of 

• Uniform Horizontal Motion
• Free Fall under Gravity

• Oblique Projection

Combination of  Uniform Horizontal Motion Vertical Projectile
