recognized that his first law needed some additional explanation because most of the motion we observe around us undergoes changes and is the result of one or more applied forces; therefore, Newton wrote a Second Law of Motion which relates force, mass, and acceleration. Newton's third law of motion is often called the law of action-reaction. In the most basic definition of a force, it is a push or a pull. Newton recognized that a force was actually an interaction between two objects; example,…
PACE Speech The problem I researched for this experiment was to see if the weight of a ball affects the speed that ball in travel at when shot or thrown. While researching this I found out that many different sports involve arm strength to throw an object far or at high speeds and many athletes don’t have enough arm strength or maybe don’t have much at all, but for every sport there is always a workout plan to increase what is needed. To increase your arm strength, the weight of a ball is a…
Superb Lyrebird page 1 of 2 Body Structure: The Superb Lyrebird is a species of Menura novaehollandiae, the Lyrebird has short rounded wings and the birds typical weight is around 2.2lb(Kg).The typical size of Lyrebird is about 100 centimeters long, for females its around 74 to 84 centimeters.The birds physical adaptations are the Lyrebirds wonderful variation of colorful feathers and keen sense of smell that allows the bird to smell out its prey. Lyrebirds colors…
the force table and put one of the pulley at the angle 35° and another at 150° Place .100 slotted mass on a weight hanger at 35° Place .200 slotted mass on a weight hanger at 150° Place another pulley at different angle from 35° and 150° On the third angle, place the amount of slotted mass so the ring will remain in center of the force. Now the ring is at equilibrium. Record the required slotted mass that made the ring at equilibrium. Record the tensions in each of the strings on the pulley.…
Calorie Intake As stated before, my client is a 22 year old female who is 5 feet 7 inches tall, weighs 135 pounds, and has a body mass index (BMI) of 21. By using the Harris-Benedict Equation in the Clinical Calculation box 22-5, I calculated that my client’s body needs a total of 1,989.60 kilocalories every day for energy (Lutz, Mazur, and Litch, 2015, p. 523). Looking back at my client’s food dairy, I can see she ingested a total of 7,000 calories in that three day period and, according to my…
Drum servo relates to drum brakes but more specifically the leading and trailing edges of the shoes. Drum brakes can have effective self-servo characteristics based upon which way the shoes are hinged, this has the effect of increasing stopping power without any additional effort by the driver because the rotation of the drum. The shoes within the drum have a leading edge and a trailing edge and are designed so that the leading edge comes into contact with the drum before the trailing edge. The…
For most of my life I’ve been fat. It’s always been a burden. The realization of being fat hit me when I was 13. I was struggling to find clothes that fit me and the solution my Mother found was to take me to the adult section and try on XL clothing, I knew that I my weight was a problem. Knowing that I was overweight still wasn't enough to motivate myself to change. For four years I lacked energy and self motivation to do something about my weight but two big events in my life occurred and…
This experiment was done to see what variables (weight, wind, friction etc.) affected the apogee of the rocket. The class did this by recording everyone's rocket weight and compared them to the apogee's after they had been launched. Due to different variables, the apogee might be affected in a variety of ways, one being the weather. After the class found all of the data, it was compared and analyzed for any patterns. The rocket had different forces acting upon it during the flight stages. The…
The atmosphere presses down on the earth an average of about 14.7 pounds of weight on every square inch it touches. Most people’s shoulders have an area of 12 square inches. So overall, the weight pressing on your shoulders is equaled out to be 176 pounds! This is called atmosphere pressure. Now it certainly doesn’t feel like there is 176 pounds pressing on me all day long, but there is an equal pressure pushing on me from all sides, including from within. In this experiment, we will…
affected by size and proximity (gravity will have a stronger pull if the object are larger and close together). Gravity also differs from the mass of an object the more mass an object has the more gravity it will exert on the objects around it. When looking at really large masses, like the earth the gravitational pull becomes much greater because of its large mass. The earth's gravitational force pulls everything towards it with the same amount of force (9.807 m/s) which in theory means that…
