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

Debate Opening Statement Can we change our impact on the rate of global warming? There are all these campaigns for us to combat global warming and reduce our emissions‚ we have all the science to maybe not stop it but effectively reduce it to stable conditions. It is evident that the temperatures and sea levels are rising and this proves global warming is out there; but it still doesn’t make a difference we still do nothing because Global warming is irreversible; we are so deep

De’Untre’ Griggs Mr. Hooks 30 September 2014 Physics/4 The Physics Of Dance Essay Physics and dance represent remarkably complementary approaches to human body movement. Those involved with dance and science can easily find the many aspects of science incorporated into the beauty of dance. With its graceful moves‚ jumps‚ turns‚ and kicks‚ dance is a representation of physics at its best and most elegant. Two dance moves in particular come to mind when I think of physics and its effects on dance. They are the grand jeté & projectile motion
