Abstract: The purpose of this experiment was to observe the motion of a projectile as a given object was launched and the forces of gravity and air resistance acted on it. Newton’s three laws allowed us to predict the motion of the small plastic sphere that was launched. In part one of the experiment, a ball was launched from a table (let h=height of table). The ball had an initial velocity of zero for the y-component (vertical); it can therefore be concluded that the same amount of time is required for a ball at rest to fall to the ground as a ball that was launched with an initial horizontal velocity. The time of flight is then calculated using the formula h=(1/2)gt 2 , where ‘h’ is the height of the table, ‘g’ is the gravitational force (9.81 m/ s 2 ), and ‘t’ is the time. Isolating ‘t’ produces the equation:

Unformatted text preview: t= 2hg . In the latter half of this experiment, the range as well as flight time were predicted using Newtons laws and then an experiment was carried out to come up with flight time and the range of a projectile launched at an angle (The angle in our experiment was 30. A ball was launched short and medium distances and the time it took for the projectile to land on a landing pad was recorded. The equation V = x/ t was utilized to determine initial velocity of the projectile. The range of how far the ball would travel was then predicted according to the equation R= V (t)(cos ) . The landing pad was placed in the expected range and then the ball was shot and observed in order to see whether it would hit its mark (the pad)....
