different masses. Obtaining the velocity, for each trial in part one, from Newton’s law would be hard because we do not know the exact degree of the force being applied to the carts. In order to derive the acceleration from Newton’s second law, we would have to have the mass of the cart and the force acting on the object. We would have to find the force first before we can apply Newton’s second law in order to find the acceleration of the cart. The results from part two show that the mass…

because it’s lighter than the others and doesn’t need as much force applied to it to travel at higher speeds than the others. To further understand my experiment you will have to know about speed, weight and the affects or air resistance. How I came up with this experiment is, knowing that different weighted balls need different amounts of force to hit higher speeds, I thought about what would happen if I applied the same amount of force to four different weighted balls. In this experiment the…

The four forces of flight are the main reason why planes fly and how they are able to glide through the air majestically. Each force of flight helps to guide the airplane to its destination by helping it withstand gravity and pressure. Lift is one of the four forces, lift is an upward force that is created by the movement of air above and below an airplane wing. Lift helps balance out the weight of the plane for it to be able to withstand gravity. Lift's air flows faster above the wing and…

evel 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…

The concept of stress dates back for centuries. Originally stress was coined as a physiological and psychological model in which an event threatened an organisms well being. Stressors trigger three bodily response changes starting with alarm, then resistance and lastly exhaustion. Eustress is a type of stress that has a positive effect on an individual. Distress will negatively affect the individual and will not be beneficial to the experiencer because it directly disturbs ones mood. (Selye,…

held end of the rubber band snaps to the other end. Mechanical energy is the sum of the potential energy and kinetic energy in an object, associated to its motion and position. An object possessing mechanical energy has the ability to do work. When a force applied to an…

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 rotating force within the drum picks up this leading edge and wraps/pushes it hard into the drum which magnifies the braking force; In conventional rear brake design only one shoe will have this characteristic. Also, the effect on the leading shoe is…

Newton’s laws.Newton’s law helps the roller coaster by adding force as well as the car’s gradually gain energy from the rise up the hill to gain more power through the last amount of the ride. I think of it like a car, the brakes will not stop unless the pressure is applied to making the object stop,and that’s what they do on the roller coaster rides. Newton’s second law plays a big role in the roller coaster ride and the second law of force and…

Stress is one of the things that almost every worker has had before. Typically stress comes from the boss pushing the workers or a big deadline. Every worker handles stress differently and most can deal with it without having too many issues. Having stress can have a long term effect on the worker health. Stress becomes a bigger issue when the worker can’t remove some of it and the stress starts to pile up. Some effects of having stress at work are being violent toward other, becoming an…

o How does this article support this main point (key ideas): Police officers are high demand in their work force has interrupted their physical well-being. The article continues to explain how the stress from their job has been negatively impacting them and how coping strategies are helping them through it. 2nd Main Point: That Serves to Prove Your Thesis: Mental…
