Projectiles essays 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 that it took the ball to hit the ground. Then taking the same ball and the same height place the ball 26m from the edge and launch it off of the flat surface. Begin timing how long it takes the ball takes to reach the ground once the ball reaches the edge of the surface. This was also done three times to find the average of the times. Dropped Launched 5. Analysis: According to the results, it shows that the average amount of time that it took the ball to reach the ground when it was launched was less then the amount of time it took the ball to reach the ground when it was dropped directly down. These results may suggest that when an object it launched it gains more speed causing it to travel faster and reached the ground quicker then an object that is just simply released. 6. Conclusion: 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? According to this experiment 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 whi ...
