VI. Answers to Questions

1. What is the effect to the result of acceleration when you lower the height of ballistic ball? The effect to the result of acceleration when the height of ballistic ball was lowered was the result of acceleration increases based on the experiment every time the ballistic ball goes down.
2. What possible reasons do you think will affect the validity of your data? Explain your answer. The time and the height of the ballistic ball, whenever height of the ballistic ball was lowered the time of falling ball decreases.
3. What can you say about the results of the theoretical value of "g" to the experimental value of "g"? is your experiment successful or not? explain your answer. The theoretical value of "g" has a big different in the experimental value of "g". Our experiment is successful because we accomplished the objective of this experiment.
4. What conclusion can you draw from the experiment. The

    There are two major concepts of physics for serving, velocity and acceleration. As the ball’s velocity increases its distance also becomes greater. Since the ball is in constant acceleration, the velocity increases by the same amount of time. With the proper velocity, the ball will hit the floor without a defender being…

    Overview: In this lab, we will test balls made of various materials. The matter that composes the ball must store energy on impact and then release the energy in a way that allows elastic recoil, or bounce. In addition to elasticity, there is also a relationship between the height from which the ball is dropped and the height of the bounce. We will measure and graph the relationship of those two variables.…

    This principle goal the scientific investigation was to see if changes in temperature expands the air inside of the basketball causing it to bounce higher. This experiment was decided by observations made while playing the sport basketball. It was observed that when a basketball is left in the sun and made warm, the ball bounces higher when dribbled than if left inside. Our assumed result was that an increase in temperature would cause an increase in air pressure causing the bounce of the basketball to increase. The independent variable was the temperature in which a basketball was in. The dependent variable was the bounce height of the basketball dropped from a height of 200cm. The variables that were kept constant and controlled were the basketball brand tested (Wilson), The temperature outside when the basketball was dropped, and the drop height used. The control group was the basketball kept at room temperature and the experimental group was the basketballs dropped when frozen and heated. To collect the data needed, three basketballs were dropped from a height of 200 cm five times each and the…

    This experiment was to use kinetics of projectile motion and free falling bodies to determine the distance a ball will travel after it hits a bounce plate. To determine this we had to use the equations x=(1/2)at2 and v=v0+at and derive an equation that will determine the distance the ball will travel based on the height of the bounce plate and the height of where the ball will be dropped above the bounce plate. The equation made was g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h)). From here we can make an estimate of how far the ball will travel after it hits the bounce plate.…

    Jenny Wilson is a buyer at Flextron, a manufacturer of large industrial pumps. She has a requirement for a customized subassembly that a preferred supplier, Vistral, is building for the first time. She is preparing for negotiation with Vistral, where a key issue will be the price of the subassembly. Given the unique nature of this subassembly, Jenny expects to incorporate into the contract price reduction targets based on learning curve estimates. While Jenny does not have specific data for Vistral, she has accumulated data for a subassembly that was similar in design and manufacturing complexity.…

    * First, combine 10.0 mL of the Ba(OH)2 solution with 50 mL of distilled water. Then, measure out 60 mL of 0.100 M H2SO4. Set up a conductivity probe and open programs by connecting to logger pro. After that, start to titrate with increments of 1.0 mL. Keep titrating with smaller increments until it is pretty close to the 100 microsiemens/cm mark. Calculate the lowest value. After that, record the volume as the equivalence point. Finally, filter and measure the mass of the barium sulfate precipitate.…
