2.4 Galileo Galilei: Sixteenth-Century “New Scientist” 1. In your own words explain why Albert Einstein considered Galileo to be the “father of modern science” Albert Einstein considered Galileo to be the father of modern science because of how many of Galileo’s discoveries have become the basis of today’s science. 2. Why did Galileo choose to use a ramp to perform his acceleration experiment? Technology during Galileo’s time was still quite primitive. His experiment which required him to drop

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

The Importance of Physics to Society Physics - the study of matter‚ energy and their interactions - is an international enterprise‚ which plays a key role in the future progress of humankind. The support of physics education and research in all countries is important because: 1. Physics is an exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about Nature. 2. Physics generates fundamental knowledge needed for the future technological advances

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

copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of wire. This magnetic flux is designated by Bi . The strength of the magnetic field induced by the current at the center of the loops of wire is given by Amperes law: Induced Bi = [pic]. where μo is the permeability of free space and has the value of 4π x 10-7 N/A2‚ N is the number of turns of wire‚ I is

Applications of Physics in Everyday Life By Steve Johnson‚ eHow Contributor Even walking manipulates physics‚ allowing people to proceed in a state of "constant falling." Physics extends well into people’s everyday lives -- imprisoning people within its forces. From each step a person takes to the evolution of the body‚ physics has several long-term as well as short-term effects and uses. For everyday living‚ many technologies have even exploited the rules of physics. 1. Simple Mechanical
