Motion in a Plane
Class 11 · Motion in a Plane
Projectile: Angle Variation
Change angle θ and speed u — watch the parabola update and read R, H, T live.
Key Notes
01
Projectile motion = uniform horizontal motion + uniformly accelerated vertical motion.
02
Range R = u² sin(2θ)/g, max at θ = 45°.
03
Max height H = u² sin²θ/(2g). Flight time T = 2u sinθ/g.
04
Complementary angles (θ and 90°−θ) give the same range.
Formulas
Range
Horizontal distance.
Max height
Peak altitude.
Time of flight
Total air time.
Important Points
θ and 90°−θ give same R but different H and T.
