The video tutorial explains the concept of oblique launch by separating the motion into horizontal and vertical components. It discusses how gravity affects these motions, with the horizontal motion being uniform and the vertical motion being uniformly varied. The tutorial also covers the initial velocity and angle of launch, and how these factors influence the motion. An experiment is conducted to determine the acceleration due to gravity and the initial velocity of a ball. Data is analyzed using Excel to fit a parabolic curve, and equations are used to calculate various motion parameters.

Why is it important to separate the horizontal and vertical components of projectile motion?

• To reduce air resistance
