Projectile Motion

Trajectory
The path traced by a projectile projected from a height above the ground is Parabolic in Nature

y = (tanθ)x - [g / 2u2cos2θ]x2

Features of Projectile Motion
 * 1) The path is Parabolic.
 * 2) The horizontal Velocity is always constant.
 * 3) The vertical velocity decreases and then becomes zero at maximum height and then it's velocity increases.

Time of Flight
t = 2usinθ / g

Horizontal Range
R = u2sin2θ / g

Maximum Range = u2/g

Maximum Height
H = u2sin2θ / 2g

Projectile Motion on an Inclined Plane
θ = θ - α

g = gcosα

Time of Flight = 2 u sin(θ - α) / gcosα

Maximum Height = u2sin2(θ - α) / 2gcosα

Horizontal Range = 2u2sin(θ - α)cosθ / gcos2α

Tips and Tricks

 * 1) Projectile Motion questions can be handled by using Kinematical Equations, keeping x & y components in mind.
