Practice question
Question
In projectile motion, what is conserved throughout the trajectory if air resistance is negligible?
Explanation
Projectile motion splits into horizontal uniform and vertical accelerated motion per NCERT Chapter 4. Range R=u²sin2θ/g and max height H=u²sin²θ/2g. Using given u, θ, g, calculation yields Total mechanical energy. Hence option B satisfies projectile formulas.
