Module 2 Honors Extension: The Physics in Swimming Physics is defined as the branch of science concerning the study of matter and energy and the interactions between the two. Physics tries to explain the nature of the world around us‚ how things happen and why. Swimming displays some physical properties‚ such as buoyancy‚ drag resistance and propulsion. We swimmers are at a constant battle to stay afloat‚ while fighting through the water and propelling ourselves forward‚ and we do so using technique

The independent variable is the rise of the ramp‚the dependent variable whether or not the marble will loop the loop. The underlying principle of all roller coasters is the law of conservation of energy. When a roller coaster crests the first big hill‚gravity takes over. Potential energy is sometimes known as positional energy. As the roller coaster falls is has enough kinetic energy to make it through the remainder of the ride. Inertia keeps the object in motion. The other forces bring the roller

I absolutely love jumping on the trampoline but I never really thought there was any physics involved. I knew you had to use a force to jump up and gravity pulls you back down obviously. An American inventor named George Nissen first invented the trampoline in 1935. (Silvia) A trampoline is defined as an elastic disc of hard canvas held up by metal springs attached to a metal skeletal frame. Kinetic and Potential energy allow you to be able to jump on a trampoline. PE=mgh this equation helps you

Cocker and Walton Prizes 2012 Physics in Medicine By Fayaz Rahaman ➢ Introduction Physics is about understanding the laws that govern the world around us. Most people know about the problems solved and the discoveries made by physicists in the past‚ such as the orbits of planets found by Galileo‚ the law of gravity first unravelled by Newton and later extended by Einstein. It is not as widely

The Physics of Badminton Gerard Ramos Physics 4A Prof. Scott Hildreth I would like to start off with a light introduction to the sport of Badminton. Badminton is a sport that isn’t too popular in the United States; some people would even say that it shouldn’t even be called a “sport”. The majority see badminton from a “back-yard sport” point of view‚ part of this is due to the lack of actual badminton court facilities in America‚ also because it’s a bit expensive to play. Badminton is not

surface‚ accelerating because of an unbalanced force. The rate at which an object travels down the slope is dependent upon how tilted the slope is; the greater the tilt of the plane‚ the faster the rate which an object will slide down. Thus‚ if a physics cart is released on at a steep slope‚ the acceleration of the cart is expected to roll down the slope at a faster rate. As shown in figure 1‚ when a cart is released on an inclined plane‚ there’s always two to four forces acting upon the cart – the
