Paintballs at a lower temperature will shrink and shoot farther because of less mass. In order to test this I will take 10 paintballs and put them in the freezer for 6 hours at 40 degrees, then 10 more and put them in the oven at 110 degrees for the same amount of time, then ten more at room temperature for the same amount of time. After the time has past i will have 2 people shoot 5 of each at targets to see which will shoot farther.

This soccer science fair project serves to acquaint students with basic information on how the amount of air in a soccer ball can affect the distance it travels when kicked with a consistent force. The greater the air pressure in the ball, the farther it will travel when a force is applied. In the process of conducting the research, the student will learn that atmospheric pressure may also affect how far the ball will travel. The student will learn about the relationship between air pressure and friction: the lower the friction, the farther the ball will go. The student will learn about concepts like air pressure, gravitational force, compression and expansion of air molecules, potential energy and kinetic energy. This science fair experiment

Based on the results of your experiment, would you reject or accept the hypothesis that you produced in question 1? Explain how you determined this.

Section Heading: The reason I think the golf ball will go the farthest is because it has the most density and density means “to have the degree of compactness of a substance.”I believe the tennis ball will go the second farthest because it has almost little density and it has no core at all and it's hollow.When the ball is hit with the most density it will give it the weight and power to travel great distance but unless the ball has to much weight it won’t go far.The baseball has the least greatest density so I gathered information

9. The total energy is constant for most of the time until the ball is released and caught up and down in free fall, because extra force of the person actions changes the energy. The energy should remain constant because the kinetic and potential ratio energy

ball that has been hit is .42 second. Their reaction time depends on a number of things. Such as

Snow globes are made of clear glass, a transparent sphere with a scenic view and a plastic toy inside the globe. The globe must be shaken to actuate the snow so the white particles can fall gradually to reach the base. When the marble (object used for this experiment) falls, it experiences two external forces which are; the gravitational force and the aerodynamic (fluid resistance) drag of the marble, which affects the rate of the marble. As the marble is falling, the speed is increased due to the gravitational force, which is pulling the marble downwards to the base of the beaker until it reaches the terminal velocity, where both external forces are equal. However, there are factors that can affect the marble’s terminal velocity, such as

“Playing basketball can be hard work. Players not only have to run around the court, but just dribbling the basketball takes some serious effort, too.” (“Surface Science: Where Does a Basketball Bounce Best?”). Energy reserved inside the ball, transfers into Different types of energy (ex. Heat, sound) when the ball hits the ground. But, which type of court restores the most energy back into the ball?

2. Rub an inflated balloon against your hair and then try to stick it to the same objects you used for Step A. Does rubbing with fur work as well as, better than, or worse than if you rub the balloon against your hair instead?

The purpose behind the egg drop project is for students to understand the concept of momentum, collision, impulse and force. To do this, they will create a protective carrier that will surround the egg. The egg will then be dropped from a certain height. The device that is created should weigh enough to increase the time of impact, therefore decreasing the force of impact on the egg so it doesn’t crack.

Let A be the event that the first toss is heads, and B be the event that the third toss is heads. Are A and B independent? Why or why not?

controlled variable- throughout this experiment is that i will use the same kind of ball, i will use the same force to hit each trial and i will measure it with the same tool.

Josh McAninch Science Project Research Paper Science Project Research Paper This experiment will find if the temperature of a baseball would affect the velocity of a pitch. How will this experiment be done, and what is the science behind it? The baseball is the main object in this experiment.
