rely on Earth’s gravity to get the cars down the track? Roller coasters are centered all on physics and I will hopefully teach you some things‚ big or small about them today. In this essay we will be exploring the world of roller coasters. Some of the topics we will cover will range from the history‚ to the principles that allow the cars to continue throughout the length of the track‚ and the general physics surrounding roller coasters. The history of roller coasters is a very interesting and long

slow constant speed across the screen. What do you notice now about the vectors? Explain why this happens. While moving the ball at a slow constant speed across the screen‚ I noticed that the velocity is constant. This happened because there was no acceleration. It was just a very constant slow speed. 5) What happens to the vectors when you jerk the ball rapidly back and forth across the screen? Explain why this happens. When I jerked the ball back and fourth‚ the velocity changed quickly

components. We calculate the components of the vectors to be added. For the coordinate system selected we have: vnet x = vbx + vrx = 3 + 0 = 3 mph ; vnet y = vby + vry = 0 + 4 = 4 mph The answer for the net velocity can be specified in two equivalent ways. One way is to specify the two components for the net velocity (as done above). The second method is to state the magnitude and direction for vnet. |vnet| = 3 + 4 2 = 25 = 5 mph. The direction is given by an angle. From the figure we see we have

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

In 2007‚ the United States of America Energy Information Administration researched that eighty seven percent of global energy consumption comes from fossil fuels. The worlds most reliable industries provide fuel and electricity to modern societies and have made millions. People have high consumption lifestyle revolving around

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
