Projectile Motion Analysis

The video tutorial explains projectile motion using kinematic equations. It covers the trajectory, initial conditions, and the separation of vertical and horizontal components. The tutorial demonstrates how to calculate the time of flight, range, and height of a projectile, using a football as an example. It emphasizes the importance of understanding both vertical and horizontal aspects to solve projectile motion problems.

What are the two kinematic equations used to analyze projectile motion?

• Definition of acceleration and displacement equation

• Newton's First Law and Second Law

• Law of Universal Gravitation and Hooke's Law

• Conservation of Energy and Momentum
