Question

what is equation of trjectory?

Answer 1

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.

Answer 2

\[y=xtan \Theta -(gx ^{^{2}}\div2u ^{2}\cos ^{2}\Theta )\]

Answer 3

There are several equations that apply to projectile motion. A two of them are:
v2 = v1 + at
x2 = x1 + v1t + (1/2)at^2

Answer 4

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
