physics paper work 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: physics is and exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about nature. Physics is the most basic of the physical sciences. From chemistry and geology through to biology and cosmology

In soccer‚ the length of the ball in air when it is kicked is the hang time. Air resistance or adding a curve to the ball will increase its hang time. Hang time can be calculated by H= 1/2 g(gravitational acceleration)times t(time) times 1/2. As the player kicks the ball with the inside of his foot he creates a curve on the ball and increases hang time due to air resistance acting on it. Kicking the ball straight will have a low hang time and just keep it low to the ground. The higher the ball is

PHY 305/601 Classical Mechanics Assignment No. 1 1. Consider a particle of mass m constrained to move on a frictionless cylinder of radius R‚ given by the equation ρ=R in cylindrical polar coordinates (ρ‚ φ‚ z). Besides the force of constraint‚ the only force on the mass is force F=-kr directed toward the originUsing z and φ as generalized coordinates find the Lagrangian L‚ solve Lagrange’s equations and describe the motion. 2. Show that the kinetic energy of any holonomic mechanical system has

Investigating Newton’s 2nd Law of Motion using an Air-track Introduction: My experiment is investigating the Newton’s 2nd law of motion by using an Air-track. The air-track can make the trolley frictionless by testing the velocity with different weights and shows that F=ma. Research question: How much acceleration does the frictionless trolley has? Aim: Use the air track to measure the acceleration of the no friction trolley by hanging with different mass of weights. Apparatus: *

communication‚both the child and parent try to understand each of their feelings and actively listen. In contrast‚ negative communication is discouraging the person and their feelings. People who use negative communication tend to be thinking only about themselves instead of trying to help the other person. Negative communication can lead to a low self esteem and the child won’t want to communicate openly anymore. 1. 4. How can divorce affect children? Divorce can affect children in different
