The scientific investigation process on a softball will be tested according to Newton’s first law, as noted by (Hutchison, 2011), “An object at rest will stay at rest and an object in motion will stay in motion at the same speed and going the same direction until acted upon by some outside force. ” In softball it is believed a ball pitched at a fast speed will be hit with a bat at a stronger force and travel farther. My hypothesis is a ball going at a slower speed will have a greater impact when connection is made with the bat and go farther.

This test will be conducted on an eight-year-old female eighing 55 pounds. Facts show, “bat-ball collision is based on the ratio of the ball’s velocity after impact to its velocity before impact,” as noted by (Russell, 2012). Newton’s first law is a testable theory for a softball.

It will stay at rest if not in play, but when a ball is picked up and thrown, it is considered changing its motion with force. When a ball is hit by a bat, it is changing the ball’s direction and speed from the initial speed by which it was thrown from the pitcher.It is important to create a testable question, hypothesis, and prediction before conducting a scientific nvestigation because the claim has to be a testable to observe, interpret, and draw a conclusion. The main purpose of a hypothesis is to make an educated guess and testable prediction about what will happen, as noted by (Science Buddies, 2010), “To prove or disprove your hypothesis, you need to be able to do an experiment and take measurements or make observations to see how two things (your variables) are related. You should also be able to repeat your experiment over and over again, if necessary. The scientific tools to use for a laboratory investigation depend on the roblem trying to be solved or tested. The variables are a key factor in the tools needed as well. For the softball theory to be tested a person must look into the amount of force needed to compress a softball at fast and slow speeds.

The mass and stiffness of a softball and the ratio’s of a softballs speed after hitting a fast and slow pitched softball. Graphs can be used to show data comparisons, percentages, increases, and decreases. Knowing the variables in the scientific experiment is the key factor in establishing the outcome.

Variables in a scientific investigation play a uge role in the scientific experiment process. These variables must be known in order for an experiment to be successfully tested the three main variables in the claim must be controlled, changed, and measured. These three variables are controlled, independent, and dependent, as noted by (Helmenstine, 2013), “Controlled variables are factor, which are controlled or held constant throughout an investigation. They are kept unchanging so they will not influence the outcome of the experiment by changing. The independent variable is the one factor that you purposely change in an experiment.The dependent variable is what is measured to determine if it is affected by a change in the independent variable. ” The controlled variable in the softball theory is the eight-year-old female weighing 55 pounds.

The independent variable is the speed change of the softball when pitched. The dependent variable is the distance the softball travels when hit at the different speeds. Observation and Data gathering aid in drawing a conclusion for the other two because these steps are all a part learning more about the experiment. These steps are a part of the process of conducting a successful test and obtaining n outcome.

When data is collected graphs are an excellent way of keeping track of results. To determine the type of graph to use will a person must know what type of results to present. The type of graph I will use is a bar graph or comparison chart because the results that will be presented are the difference in distance compared to the two different types of speeds that are pitched. The results obtained from the test will be the conclusion and can be compared to the original hypothesis. The relationship between the two is the hypothesis is what a person thinks will happen, and conclusion is the outcome of the experiment or what did happen.

For the softball experiment the hypothesis is a softball pitched more slowly will be hit harder and travel farther. The outcome of this experiment is a ball pitched at a greater speed compared to a slower speed does travel a farther distance because of the amount of force exerted when hit and faster speed when pitched. This is known as the bat-ball collision.

The ball pitched at a higher speed of 40 miles per hour was hit at a distance of 1 1 5feet. The ball that is pitched at a speed of 30 miles per hour only traveled 90 feet. References Helmenstine, A. M.
