Projectiles

1. Title: Measuring the time of Projectiles 2. Hypothesis: If a ball is thrown and then also launched from the same height, will the ball reach the ground in the same amount of time. 3. Method: A ball was held at the edge of a flat surface, approximately 89.6m high, and then was released, timing how long it took the ball to reach the ground. This procedure was done three times in order to find an average time …

…this statement does not hold true. The results show that the object that was launched took less time to reach the ground then the object that was dropped. However, these results may vary experiment to experiment due to human error and the difficulty of timing a situation that occurs in a very small amount of time. These results of timing contain human reaction time which needs to be taken into consideration when analyzing the data.
