Kendra Wilmore Prof. Gross English 051 3/17/14 My S.M.A.R.T Goal Reaching and maintaining a healthy weight is important for overall health and can help you prevent and control many diseases and conditions. That is why I am using the S.M.A.R.T goal setting process to lose ten pounds in the next three months. I picked this specific fitness goal because I think it crucial to feel good about myself and keep a healthy weight. This goal is not going to be achieved on its own; it’s going to

line with constant speed (if its velocity is nonzero). 2.Second law: The acceleration a of a body is parallel and directly proportional to the net force F acting on the body, is in the direction of the net force, and is inversely proportional to the mass m of the body, i.e., F = ma. 3.Third law: When two bodies interact by exerting force on each other, these forces (termed the action and the reaction) are equal in magnitude, but opposite in direction. The three laws of motion were first compiled

was an outlier that caused the difference between percent difference (300%) and the standard deviation of the dataset (0.01 g/cm3). We can conclude that errors were probably made during the process of finding the volume of the copper and finding the mass of the

Data Analysis The scientific question that was asked in this experiment was,”What is the best angle to shoot a paintball to achieve the farthest distance possible?” The hypothesis of the experiment was,” If a paintball is shot at a 50 degree angle, than the paintball will travel the farther than any other angle tested.” The independent variable is the angle of degrees the paintball is shot from and the dependent variable is the distance the paintball travels at the different angles it is shot from

After conducting our experiment, we concluded that the hypothesis was correct. A change in the mass of a moving object does affect the speed of the object. We arrived at this conclusion by rolling five marbles with different masses down a small scale roller coaster and recording how long it took each marble to roll from the starting point to the ending point of the roller coaster. The data from our investigation is the amount of time it took each marble to go down our roller coaster in seconds.

on a track scholarship. She currently is working hard towards making the U.S. Olympic team. Amy is a vegan and weighs only one-hundred and fifteen pounds. Her coach is worried that she is not consuming enough protein in order to maintain her muscle mass. As an athlete, it is important to be consuming enough protein. If dietary protein needs are not met, strength of the body will decline and the athlete may experience lower energy levels. The first thing that needs to be discussed is how much protein

How does a physical or chemical change affect the mass of a substance within a closed system? Our hypothesis to this question was, if a chemical change affects the mass, then the mass will change. Our second hypothesis was, if a physical change occurs, then the mass would stay the same. Changes in matter happen all around us everyday. When we use a coloured pencil, they change in the size of how hard you are pushing on the coloured pencil which dulls it out. When you chew food it, changes its size

Throughout the first collision, the collision is supposedly elastic as when both objects collided are separated by a spring bumper which is made of steel, which is considered to be a very elastic material. In reality no collision is elastic as kinetic energy is converted to other forms of energy such as thermal energy, sound energy. Within this investigation, the air coming from the platform prevents energy loss due to thermal energy; however it also introduces air resistance which will prevent kinetic

Introduction Last week we did an experiment on how does the volume of an container affect the mass required to make it awash in water.Some concerns we had were how would we know when it would be a good time to stop adding washers. Or how do we know our trials not change. The independent variable was the size of the beaker and the dependent was the number of washers that were needed. The controlled variables were the amount of gasses in the water because its tap and the temperature of the water.
