what is equation of trjectory?
trajectory of a projectile is the path that a thrown or launched projectile will take under the action of gravity, neglecting all other forces, such as friction from air resistance, without propulsion. like this one.
\[y=xtan \Theta -(gx ^{^{2}}\div2u ^{2}\cos ^{2}\Theta )\]
There are several equations that apply to projectile motion. A two of them are: v2 = v1 + at x2 = x1 + v1t + (1/2)at^2
Trajectory is the oriented line made of the successive positions of a point in motion, relative to a specific frame of reference. The equation of the trajectory is obtained from the time equations of the coordinates of the particle*, simply by eliminating time between the equations**. * e.g. x(t) y(t) z(t) in Cartesian coordinates or r(t) θ(t) z(t) in cylindrical coordinates ** e.g. y=0 ; z=ax²+b or r=2acosθ ; z=0 in cylindrical coordinates
