Tennis ball and racquet ball comparison

Problem: Locate the speed of the tennis ball and the racquet ball to determine which one moves faster. Speculation: I believe the racket ball will have a faster normal speed than the tennis ball for both equally distances since the racket ball is bouncy. Materials:

*Tennis ball *30yards of space

*Racket ball *Set of stairs

*Stop watch*measuring tape

Techniques:

1) Evaluate out 35 yards of space, possess of member stand at one end of the field with a stop watch in hand. 2) Another affiliate throw the tennis games ball 40 yards while timing the length of time it decide on get there. 3) Repeat two more occasions and gather the average rate (total distance/ total time). 4) Repeat this process using the racket ball. Record in table 1 . 5) For experiment two, measure among the steps and multiply by how many steps you could have. 6) Have a member at the bottom of the methods with a termes conseilles and the a single with the tennis games ball at the pinnacle. Time how much time it will take the tennis ball to reach underneath of the step with the termes conseilles. 7) Do it again #6 two times more, and locate your typical speed (total distance/ total time). Record your data in Table installment payments on your 8) Replicate steps #6 and #7 replace the tennis ball with the racquet ball. 9) Compare your details in your conclusion.

Conclusion:

Within our experiment we discovered the speed of a golf ball and a racket at distinct distances. To determine the speed of the objects we all used the equation speed= distance/time; Velocity is the price of modify of a length. My group and I hypothesized that the racquet ball may have a quicker speed in experiment you and installment payments on your I thought this because the racket ball has a rubber like quality that I believed would boost its speed average. Within our first try things out, we took the racket ball and the golf ball and threw them 30 yards. We repeated these trial three time to ensure precision. For each of our second research, we positioned the racquet ball and the tennis ball to the the top of stairs and rolled them down. We all conducted the experiment 3 time and determined the speed. Once we collected the info we started to compare the results; the average for the tennis ball being put 30 back yards was and average of 7. 45 yards/second. While the racket ball recently had an average of 10. 2009 yards/ second in our initially experiment. Inside our second experiment the tennis games ball recently had an average speed of twenty three. 87 inches/ second as the racket ball had an common of twenty-one. 72 inches/second. The golf ball acquired a greater acceleration than the racquet ball in experiment a couple of while the racket ball excelled in velocity in our 1st experiment. During our test we knowledgeable wind which will hindered our second experiment. The ball would get found by a gush of wind and become caught up in the bleachers. I would guide checking the weather conditions before you commence your experience, and conduct the lab on a day with low wind prediction. The data amazed me in the fact that the tennis ball a new greater speed than the racquet ball inside our...
