Throughout your daily life, in 2016 it is almost impossible to avoid some form of stress. There seems to always be a deadline or a soccer game that requires time to accomplish. These events that occur in our life are called stressors. In the video The Stress Epidemic, they use a barking dog as an example of a stressor. If the stressor is not taking care of the end result is stress. If I had a hypothetical meeting with a client who is under stress how would I approach the situation? The first…
Popping An Ollie Physics Around Campus Ryan Meehan Physics 102 Spring 2017 This is a picture of me popping an ollie in the basement of Dooley Hall. An ollie is the first trick that many skaters learn, as it is the foundation for almost every other trick and can help skaters avoid obstacles such as small cracks and rocks that could ruin your day, and knees. The physics behind popping an ollie is very interesting, and after teaching my friends, and kids that I babysit how to skate…
friction. The friction occurs between the wheels of the car and the surface it rolls upon. I encountered a problem regarding the lightness of my vehicle. I initially used a foam base but it was too light and had little air resistance, so I switched to a heavier material that resisted the air more. I chose to incorporate four wheels upon my design because I believed it would highly balance my car and its mousetrap engine within it. In addition, it resembles an actual car, which works really well…
principles are drag, propulsion and propelling efficiency with respect to energy output. The overall key to the success of the swimmer is the ability to generate maximum propulsion efficiency with the combination of minimizing resistance. Total force of drag can be broken down into three components, pressure drag, frictional drag and wave making resistance. The pressure drag is mainly impacted by the body cross-sectional area. Frictional drag is…
dropped from a specific height it will increase in speed by 9.8 m/s (meters per second) because attributed to gravity. Once the ball touches the ground it will release kinetic energy, the force in which the ball affects the ground is measured in joules. For a fraction of a second, the ball is stationary. The air inside the ball is compressed and releases potential energy. The ball forced to push against the floor causing an opposite reaction giving the ball rebound. A prime example referring to…
“Estabrook, a freelance food writer whose work has appeared in The Atlantic, The New York Times and The Washington Post, looks at the life of today's mass-produced tomato — and the environmental and human costs of the tomato industry — in his book Tomatoland: How Modern Industrial Agriculture Destroyed Our Most Alluring Fruit. The book was based on a James Beard Award-winning article that originally appeared in Gourmet magazine, where Estabrook was a contributing editor before publication ceased…
Milca Nieto Meredith IB Physics 3 Apr 24, 2017 IB Physics Internal Assessment Report Research Question: How does the height from which a ball is dropped affect the time it takes to reach the ground? BackGround: In this experiment, the release height of the ball is the independent variable, and the time to reach the ground is the dependent variable. For this experiment, a tennis ball will be dropped from heights ranging from 0.50 m to 4.50 meters, in increments of 0.50 m. The time required for…
distorted and generate heat; such as when an egg hits a hard surface and breaks. The egg does not bounce, but instead it breaks; the momentum is transferred into the ground. The ground is the external force that is applied against the egg to make it break (Hewitt, 133). With an inelastic collision the net force of then momentum is not changed but the holding space of the momentum changes; an example is that the momentum is the same when it goes from the egg to the floor it just changed location.…
In future, beside conventional wars, military forces will have to fight against hybrid or asymmetric threats in protracted wars. It will be almost impossible to predict the future enemy with precision, and develop capabilities accordingly. Moreover, the enemies - both conventional and unconventional…
in it flew through the air more consistently than a smooth golf ball.6 Manufacturers started incorporating patterns to golf balls to try and find which gave a more stable and reliable flight pattern. In the 1900’s it was determined that the strategic placement of indentations maximizes lift while minimizing drag, thus leading to the modern day design of a golf ball. Drag and Lift In order to determine why golf balls have dimples, it is important to first look at the forces in the system as a…
