Projectile Motion Lab
Posted November 15, 2008on:
Students get a Nerf gun, a meter stick, a level, and a long metric tape measure. They launch several darts horizontally from 1 meter in height and mark where the darts first hit the ground. They measure this distance and average them together. Then using this distance and the time it takes for an object to fall 1 meter, they can calculate the muzzle velocity of their Nerf gun. (My Nerf gun in the picture has a muzzle velocity of around 12 m/s.)
Part two, they are to use what we did in class to calculate how far the dart will go if they are launched from the ground at 10º, 15º, and 20º. (Any higher angle and they hit the ceiling.)
Part three, they go back to the range and using a large cardboard protractor that I made, they launch the darts from the ground at those three angle and see how they did. The lab is attached below along with another one I do at the same time. Enjoy.
