What are the assumptions made in the study of a projectile motion ?

Text Solution

Verified by Experts

To study the motion of a projectile, we assume that (i) there is no fritional resistance of air. (ii) The effect due to rotation of earth and curvature of the earth is negligible. (iii) The acceleration due to gravity is constant in vagnitude and direction at all points of motion of projectile.
