ANSWER:
The shape of a projectiles trajectory is not called an ellipse,it is parabolic.
Step-by-step explanation:
Projectile motion is a kind of motion where an object moves in a bilaterally well-formed, parabolic path. The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force implemented at the start on the trajectory, after which the only restraint is, from the gravity.When we look at the shape of trajectory it forms a parabolic shape as discussed above.
