What are the special Points of Oblique Projectile Motion?

Special Points of Oblique Projectile Motion : (1) The three basic equations of motion, i.e. $v=u+a t$ $s=u t+\frac{1}{2} a t^{2}$ $v^{2}=u^{2}+2 a s$ For projectile motion give : $\mathrm{T}=\frac{2 \mathrm{u} \sin \theta}{\mathrm{g}}$ $R=\frac{u^{2} \sin 2 \theta}{g}$ $H=\frac{u^{2} \sin ^{2} \theta}{2 g}$ (2) In the case of projectile motion, The horizontal component of velocity $(u \cos \theta)$, acceleration $(g)$ and mechanical energy remains constant. Speed, velocity, the vertical componen...
