Answer to Question #7654 in Mechanics | Relativity for jamshed
prove that 'projectile motion is parabola'.
Let's consider the equation of a height of a flying projectile:
H(t) = gt²/2 + Vv*t + H0,
where g is the gravity acceleration, t is time, Vv - initial vertical velocity, H0 - initial height. As we see, this equation is parabolic with respect to time variable. So, projectile trajectory is parabola.
