Tides slow the Earth’s rotation speed in two ways. First‚ tides slow Earth’s rotation with tidal friction (such as bottom friction or the breaking of the waves). This effect causes a very slow‚ steady change in Earth’s rotation. It causes the rotation to slow by about 2 hundred-thousandths of a second each day‚ and it adds twenty seconds to each day every million

The Physics of Basketball Brittney LeBlanc Physics 122 Physics comes into play throughout our lives‚ in absolutely everything we do‚ especially in sports such as basketball. Although you do not need to be a physician to become a basketball player‚ if you understand the basic physics of basketball‚ it can be very beneficial to your game. Specifically‚ understanding the physics behind shooting‚ passing‚ and dribbling the basketball. A Canadian named‚ Dr. James Naismith‚ was instructed to create an

braking technology has reached a new peak. In this project electricity is applied to the coil at the time of braking. This develops a magnetic field around it and the rotating armature gets attracted towards the coil. As a result the inner and outer friction plates placed between the armature and the coil gets squeezed‚ which develops a torque and eventually the vehicle comes to rest. Further researches and studies on the braking system shows that in future‚ electromagnetic braking system can be used

force balance data. This represented a calibration error in the pressure distribution measurements. Calculations gave a maximum coefficient of lift of . The drag data showed that form drag was the largest contributor to total drag‚ with skin friction drag and induced drag having only small contributions. Javafoil simulations gave similar results of coefficients of lift for the given airfoil‚ of which closely matched the force balance data. It was determined that thin airfoil theory is only

technology has globalized the business but economically well developed countries have been more benefited. While technology has created many opportunities for global networks of tasks it is important to look at the friction in the system to understand the limitations. The sources of friction are many and could bring the

For my topic I chose to explain some of the physics involved in the sport of soccer. I chose soccer because I have played it my whole life and it is one of my favorite sports. I thought it would be interesting to learn about some of the physics involved in something that I do almost everyday and has been a big part of my life for as long as I can remember. My poster depicts the physics involved in kicking‚ the ball rolling across the field‚ and bending the ball. Kicking a soccer ball involves transferring

Drake University Abstract Robbers Cave experiment was completed by Muzafer Sherif in order to question whether groups are able to work together for a common goal for the whole group. Muzafer showed us through 3 stages a) In group formation b) Friction phase c) integration stage. This experiment was made up of 22 Caucasian middle class boys who shared similar backgrounds coming from a two parent home and protestant background. The boys were complete strangers to one another. Through the experiments

For example‚ on the balloon’s motion‚ there are points where energy is lost. When the balloon is moving‚ the friction between the string and straw causes heat‚ and thermal energy. Another example is the sound energy created during the movement of the balloon‚ the energy has been lost. In order to improve this and make it more efficient‚ perhaps we could use a string that created less friction and then would result in a faster balloon
