Lab #3 PROJECTILE MOTION PURPOSE The purpose of this ballistic projectile motion laboratory was to use vertical and horizontal components of the initial velocity of an object being shot out of a projectile launcher to calculate the distance the object traveled, as well as it’s velocity through the air. MATERIALS Ballistic Projectile Launcher Ruler/Yard Stick String Carbon Copy Paper Timer PROCEDURE 1. Initial velocity was first calculated by measuring the distance between the two timer gates ( d ), and the time it took for the projectile to travel between the two gates ( t v ). 2. The distance between the floor and the projectile launcher ( h ) was recorded at both 40 o and 20 o . At each angle, the projectile was launched and the point at which the projectile hit the floor was marked using carbon copy paper. 3. Next, the distance from the projectile launcher to the point on the floor ( R ) was recorded. This measurement was taken by running a string straight from the point on the floor to a weighted string hanging directly below the projectile launcher. The string was then measured on a yard stick.
