My testable question is an off the ground spike more powerful and faster than a spike that is done on the ground. I will answer this by spiking the volleyball ten times, five times in the air and five times from the ground. I will be ten feet away from the wall and I am going to measure how high it bounces after it touches the ground. I chose this topic because I love volleyball and I wanted to know which position has more force and power. My hypothesis is “If an off the ground spike is made,…

Conclusion The initial hypothesis was rejected. The hypothesis was if the mass of the baseball bat affects the distance the baseball will go, then the heavier the bat is, the further it will travel. The average for the 283.5 gram bat was 49.2 meters. The average distance for the 396.9 gram bat was 52.29 meters. The average distance for the 595.34 gram bat was 50.84 meters. The average distance for the 708.7 gram bat was 45.5 meters. The results mean that the heavier the bat, the less distance…

When they round the brow of the first hill, the force of gravity makes them hurtle energy as well. Even the rattling noise the rollercoaster makes uses up some of its energy. The cars lose more and more of their original energy the longer the ride continues, and, since the cars have no engines, there's no way of replacing it.…

Introduction: Every company wants to improve the quality of their product which in turn will increase the market potential of their product. Food companies are also among those companies those have always tried to develop new ways to provide fresh and healthy foods to their customers. In this process, they have to face some difficulties. These difficulties usually happen in the sorting phase of foods. Everyone knows after the passage of time, every food item loses its freshness. As a result, it…

“To get into the bowl or not to get in the bowl.” That was the question of the hour, as construction on Skittle Hive began, for it landed in the bowl it would be a reward with a glory and honor, not to mention a cool ten points. To do this many things had to be considered, such as elasticity constants, and the energy that was being used. Once that was done the catapult had to be made and tested on angle and how far it could firer. Then it was ready, ready to fire and reach for the skies or maybe…

Projectile Motion Worksheet A ball rolls off a desk at a speed of 3.0 m/s and lands 0.40 seconds later. How far from the base of the desk does the ball land? How high is the desk? What is the speed and angle of impact? A slingshot is used to launch a stone horizontally from the top of a 20.0 meter cliff. The stone lands 36.0 meters away. At what speed was the stone launched? What is the speed and angle of impact? A ball rolls with a speed of 2.0 m/s across a level table that is 1.0 m…

Experiment 3: Buoyancy Introduction Mass is described as the measure of the amount of matter contained in an object. On the other hand, weight is the measure of the force of gravity acting on the mass. Mass is measured in kilograms, while weight is measured in newtons. The density of an object is found by dividing the mass by the volume. Buoyancy is the upward force of a liquid which counters the weight of an immersed object. The theoretical buoyancy of an object can be calculated by using the…

When a ball is kicked at its side it begins to spin around in its place according to the location of the kick. If it is kicked at the side and a bit towards the bottom the ball rises up in the air while spinning on its own axis. In the beginning it will fly exactly in the direction of the kick, and as it slows down due to friction with the air, the spinning motion will cause the air on one side to move faster than that on the other side and because of the Magnus effect the ball will then change…

The swing of a baseball bat, the sound of it gliding through the air, the swoosh sounds as it swings by. Now there is something used for a job that is closely related with the baseball bat but a bit more tactical and is in the law enforcement and requires a police baton, which is used for both law enforcement and self defenseive techniques. The type of police baton should be chosen carefully due to its affordability, length, and the material it is made from so that it’s helping out with the job…

Hydroelectric energy is made from a turbine that turns falling water into mechanical energy; then that mechanical energy is turned into electric energy. This process helps produce electric energy from the kinetic energy of falling water. How does this process involve chemistry? It first begins with the mechanical energy of the water. Mechanical energy is all the energy that is put upon an object. In the case of the hydroelectric generator, the mechanical energy is made from the position of…
