Finding the Acceleration of a Ball Problem Statement: How does the height of a ramp that is comprised of two parallel rulers affect the speed of a steel ball bearing rolling down it? Hypothesis: If the steepness of the ramp based on the amount of books propping it up are increased‚ then the steel ball bearings’ speed will increase. Materials: 2 wooden meter sticks 1 steel ball bearing 5 workbooks A roll of masking tape A stopwatch A smooth‚ long surface (preferably a table) Procedures: Arrange

before and after the ball in the P.E.E/C.C.C format: Leila the protagonist and the main character of the story "Her First Ball" is described as a girl who lives in an area that is quite isolated from the excitement of the city. In fact‚ she even says that her closest neighbor lives 15 miles away. This is why this event‚ her first ball‚ is such a rare and an exciting occasion for a girl like her. In this essay I will be explaining how her thoughts and feelings before and after the ball changes. Before

In the operation process of ball mill‚ steel ball is an important factor to affect the output of ball mill. Many casting ball users only add casting steel balls according to their experience. This often causes unnecessary loss. As casting ball sales personnel‚ one must have an understanding of scientific and rational adding ball methods in order to guide the customers how to add ball into ball mill professionally. In this essay‚ we will talk about how to add ball in a suitable way. Why do we

factor that affects the height of a bouncing ball. The factor that will be investigated in this experiment would be the initial height of the ball. The relationship will be determined by altering the initial height of the ball prior to the release in order for the ball to bounce. The ball used in this experiment would be a tennis ball‚ and it will be dropped on the same surface each experiment. However‚ the initial height prior to the release of the ball will be altered in order to determine the true

the Golf Ball One factor that greatly affects the flight and trajectory of a golf ball is the air resistance. People may think that air resistance would make the golf ball slower and drop faster‚ but this is not true. Modern golf balls have adapted to this by having circular shallow depressions‚ also known as “dimples‚” on the ball. This was invented by a English engineer William Taylor in 1908. Unlike other designs‚ the dimple proved to be the most aerodynamically efficient. Dimpled balls fly farther

Interpretation of Results The objective of the experiment‚ entitled Newton’s Second Law of Motion‚ is to verify the direct proportionality of acceleration and net force if the mass of the body is constant and to verify the inverse proportionality of acceleration and mass if the net force is constant. It is now clearly explained and proven that Newton’s second law of motion is true. By experiments‚ the law is proved. All data produced results parallel to what Newton states. We can say that the
