What does “Projectile motion” actually mean in Kinematics, and why does it matter for JEE?
motion under gravity where horizontal and vertical motions are independent — horizontal a=0, vertical a=−g.
In simple words: motion under gravity where horizontal and vertical motions are independent — horizontal a=0, vertical a=−g. Getting Projectile motion clear matters because JEE questions on Kinematics usually test this idea directly, not just a formula you memorised.
Key point
Projectile motion
Common mistake
applying v=u+at to the whole velocity instead of resolving into x and y components.
Memory tip
split every projectile into a horizontal (constant-velocity) and vertical (free-fall) problem.
