    Essay On Physics In Golf

    Physics is more around us than one would think. Physics is in all of the things you love to do. Take golf as an example there is velocity in a golf swing. Velocity is the speed of something in a given object and the speed of your club in the direction you are aiming is velocity. Also there is gravitational potential energy in the top of your backswing to cause you to pull the club downward. Kinetic energy is also in golf, During your backswing kinetic energy is causing your club to go up and in your downswing all of the potential energy is turned into kinetic energy before you hit the ball. Friction is also involved in golf because friction is the force of two objects rubbing against each other and when you hit the golf ball of the ground your club and the ball are rubbing against each other to make the ball go farther. Also when the ball hits the ground the ball and grass are rubbing against each other to cause the ball to slow down.…

    Finding Mass Using the Inertial Balance

    Theory: Physics can be referred to as the study of various properties of matter and energy. Matter can best be described by looking at the mass of an object. Mass is the amount of material that is in an object. Mass can be found by using a spring scale, a balance scale, or an inertial balance. Inertia is the resistance by mass to any change in its state of motion. Scientific Law states that mass and inertial forces are directly proportional. The purpose of the inertial balance is to measure the different inertias between different masses therefore providing a mathematical and very accurate method of measuring mass. Experimentation showed that if a mass was put into some form of periodic motion, the mass could be measured fairly accurately by measuring the oscillation period and comparing it to a known mass period. The relationship m1=m2T12/T22 was discovered.…

    New Paradigms in the Study of Physics

    Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific Revolution in the 17th century, the natural sciences emerged as unique research programs in their own right. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms of other sciences, while opening new avenues of research in areas such as mathematics and philosophy.…
