Experiment 6: Work, Power and Energy Laboratory Report

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

1. When we say that something gives us “energy,” what does that mean? What is a biological definition of energy?

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

Energy is the strength and ability that is required in order to perform physical or mental activities. There are different forms of energy these consist of: magnetic, kinetic, heat, light, gravitational, chemical, sound, electrical, elastic and nuclear.

C. An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide.

Are forth step was the basketball to be hit by the tennis ball and fall through a hoop. This step had potential and kinetic energy and force. The tennis ball used the force from the baseball to hit the basketball. The basketball was storing up potential energy while the rest of the machine was running. When the tennis ball hit the basketball the potential energy was released. As the basketball was falling through the hoop it had kinetic energy.

Moving along, to the second experiment, “How does force affect your game?” concludes that using a 10 pound ball applying strong force provides a velocity (m/s) of 3.2, a result of 25 (J) for the kinetic energy, and 5 bowling points

This project deals with the effect of different gases on a football’s “hang time.” Hang time refers to how long the football is in the air. Five Wilson Touchdown Official footballs were bought from Target online and shipped to the researcher’s house. Then, four twenty liter cylinders of industrial grade gases were bought from Airgas online and shipped to the Southwest Virginia Governor’s School. The gases were Nitrogen, Helium, Argon, and Carbon Dioxide. Before this experiment was done, the footballs were filled with the different gases. The filling of the footballs were done in Mr. Frazier’s physics room at the Southwest Virginia Governor’s School. The first step in order to fill the footballs was to clamp one of the Helium gas cylinder to

The purpose of this experiment was to investigate the effects of different masses hoisted by an electric motor from ground level to a height of 1.29 m. The main purpose was to look how a change in mass affected the efficiency of our motor, but it did affect other variables such as power, current, force, etc. For this experiment, our hypnosis is that as mass increases, the efficiency increases. Because in the equation for efficiency, efficiency=gain in potential differenceelectrical energy used, gain in potential difference = mgh, the mass of an object has a direct relationship with the efficiency of the motor. In this equation, we see that efficiency is affected by the mass that is lifted, gravity, the height the mass is being lifted, and the amount of energy that is put into the system. We can see that mass, gravity, and height has a direct relationship while inputted power has an inverse relationship with efficiency.

INTRODUCTION Energy is the ability to do work. It can transform into different types of energy such as potential and Kinetic. Potential and Kinetic energy are two opposite types of energy. Potential is energy of position-when an item is unmoving it has the potential to move. Kinetic energy is energy of motion-as the item is in motion it is converted to kinetic.

In Hitting a Baseball: A Biomechanical Description, they mentioned that researchers have studied bat dynamics, and described the bat’s movement during the swing, using the software we use in class, the three-dimensional components of its motion (Welch, 193). The movement and coordination of the body during the swing has always been the most difficult thing to account for during this study. Compared to other movements, there hasn’t been many studies on the kinematics and kinetics of the baseball swing. In the Biomechanical Analysis of Baseball Hitting, they mentioned the analyzation of the relative angular movement of the bat prior to that sweet sound of laces and lumber. They found that the bat had a drastic increase in the rate of velocity before it made contact (Hirano, 21). Many other studies have been done, however, these two were the two journals that seemed to have the most reliable

The purpose of this project is to analyze an overhand volleyball serve from a biomechanical perspective. Biomechanics is defined as forces and movements on living systems. It looks at the internal and external forces that act on the body, and the movements that these forces create. By understanding the biomechanical concepts, you can train your body to move with accuracy. It also enables us to develop new skills, correct minor mistakes, develop new equipment design, and improve safety to reduce the risk for injury. The volleyball serve almost looks like a throw-like movement because the joints used extend one after another. The reason behind this is that within the movement, the shoulder extends before the elbow and wrist; the shoulder actually begins to extend while the elbow is still

There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.

All of these require energy, and energy is what physics is all about. There is kinetic energy, potential energy, conservation of energy, velocity, acceleration, mass, force, and gravity. Energy gives you the ability to do work. Energy is everywhere in nature

Gottfried Leibniz first coined the term energy from the concept vis viva to refer to the square totality of an object’s mass and its speed, where total vis viva is stored. Energy is
