Year 12 students from Assumption College English Program study the effect of the elevation on the range of a projectile.
Theoretically, the trajectory of a projectile will follow a parabolic path with the range being a function of the initial velocity (u) and the elevation (θ): viz. R=u^2.sin (2θ)/g. So the maximum range will occur when sin (2θ) is a maximum ie. θ=45 degrees.
The students proved this by adjusting the elevation and measuring the range of the projectile . The results were tabulated and then plotted on a graph of elevation vs range. The data formed a smooth parabolic curve with a maximum around 45 degrees.
