Discussion The results above show that the Calorie counting diet was the diet which had led to the greater weight loss. Weight loss occurs because the body, eats less and burns more calories, this process is called calorie deficiency. The calorie counting diet was the most effective for weight loss over the 3 week period, the diet itself was sending the participant into the first stages of nutritional deficiency, unfortunately this sent the body into a starvation like mode. This is when the body

Conceptual Questions If you pull a tablecloth very fast from underneath a table setting, given minimal friction, the dishes will not move from their original position. Describe this trick in terms of Newton's first law. When you quickly pull a tablecloth from a set table, the items will remain in place on the table due to Newton’s first law regarding inertia and the tendency for objects that are at rest to remain at rest. When the cloth is pulled perpendicular to the force of gravity, and if the

Josquin Des Prez is a composer from the renaissance era from 1440 to 1521. During Josquin's time in the renaissance era he acquired the title of the greatest composer of his day. His style(Polyphonic) of composing became universally imitated and admired as his mastery of the technique grew. Writers wrote about his reputation and fame and theorist held is work as the best representing perfection such as Heinrich Glarean. Compositions were attributed to Josquin anonymously by admirers, to try

human being, causing injury. Even after a human body comes to a stop in an accident, its internal organs continue to move, slamming against each other because of the impact, often causing serious injury or death. Newton’s second law of motion, force = mass x acceleration, conveys that as the time it takes for an automobile to

Battling Bulimia? This Is What It Can Do To Your Teeth Bulimia is a serious condition where you constantly alternate between gorging on food and then vomiting it back up. It can destroy your health because of the lack of nutrition your body receives. Bulimia is also very hard on your teeth. As part of your recovery from bulimia, you'll need to work closely with your dentist to repair damage to your gums and teeth in order to restore your oral health. Here's what you need to know about bulimia and

Water Jet Target Characterization and Relation to Conservation of Linear Momentum Stephanie Coleman July 7, 2015 2 Abstract In order to visualize and conceptualize the affect of the contact angle on impact force, testing of four different shapes and comparing the results was done. Conclusions were drawn on the affects of the type of contact surface on the measured impact force. In analyzing these results, it was also be of interest to calculate the theoretical force using a derivation of equations

1. INTRODUCTION In this experiment we learned Newton's Law. Newton's first law stated an object at rest stays at rest and an object in motion keeps moving with a constant velocity until/unless a net external force. Newton's second law stated a equation F ⃗=ma ⃗ and the third law stated for every action there is an equal and opposite reaction. We have also learned steps such as, draw free body diagram with labels, write Newton's equations and solve the equation in order to find the result. The purpose

How does kinetic energy affect the stopping distance of a small vehicle compared to a large vehicle? Because the smaller car has a smaller mass, you will require less kinetic energy to stop it compared to the larger car which requires more kinetic energy because of its larger mass. 4. Keeping in mind the kinetic energy of a moving vehicle, how can a driver best prepare to enter sharp curves in the roadway? Before entering a sharp curve, the kinetic energy of

As I was waiting for my doctor to enter the examination room, I could not stop thinking about the scale. Many people, including myself, usually dread going on the scale, but today it was different. It had been two months since my last appointment and I was ready for the results. A year ago I consulted with a Dietician to help me with my eating habits. I always try to eat healthy foods such as fruits, vegetables, lean proteins, and whole grains; however, I never know how much I should be eating of
