IB Physics HL Lab Report on Projectiles

Aim

To find the optimal launching degree for projectiles.

Method

To prove that 45 degrees is the optimum angle for ballistic, we are going to calculate, measure and compare the distance travelled for 30 degrees, 45 degrees and 60 degrees.

Please take note that the mathematical demonstration of 45 degrees as the optimum is included in annex.

Accordingly, from the mathematical proof, we can say that 45 degrees is the optimum inclination for distance travelled horizontally by a projectile.

Data Analysis

Methodology: Equipped with a water hose, with the water tap on and a water pressure of about 10m/s, we measured the horizontal distance travelled by the water spurt in the school backyard. Due to the lack of space, we could only proceed with the experiment once.
