Stress is a state of mental or emotional strain or tension resulting from adverse or very demanding circumstances (Webster). Located at the center of the nervous system is one of the body’s most important organs, the brain. The brain is an extraordinary part of your body as is it processes every thought you have, and every word you say, by sending signals through your nervous system. There are many disorders that can inhibit the brain from functioning normally, however the one thing that can be…

Isaac Newton had a rough childhood. He was born December 25, 1642. His father died before he was even born, and at the young age of three, his mother left him in the care of his grandmother to go remarry. His mother had three more children with her new husband, so that made Isaac, one of four kids. He went to school at the ages of 12-17, and was then pulled out to help farm. After that, he was admitted to college with the help of his uncle, where he was awarded a scholarship. That scholarship…

If Isaac Newton was to watch the clip from Star Wars, there would be many reasons why he would be sad. Many aspects of the clip go against his laws, Therefore, making Newton sad. One example is that in the video there are ships flying. However, because there is no air in space, there is no air resistance, meaning there is nothing pushing against the ships so that they could fly. In Newton’s first law, he states that “Every body perseveres in its state of rest, or uniform of motion in a right…

The foot and ground exert an equal and opposite force on each other. This is known as the ground reaction force.12 The position and acceleration of the runner's center of mass regulates the direction and magnitude of the ground reaction force. For instance, a runner sprinting from a standstill. Throughout the initial phase of acceleration, the body is inclined forward and therefore the center of gravity falls in front of the contact surface. After many gait cycles, the runner reaches top speed…

Reflect and evaluate your application of biophysical principles to learning physical skills I have been learning to play volleyball for a term during two fifty-minute sessions per week. I have chosen to specifically focus on two skills that I have learnt – the dig and set. The biophysical principles that have contributed to learning, developing and improving these skills are force summation, balance and stability, stages of learning and feedback. The biophysical principle that contributed the…

My testable question is an off the ground spike more powerful and faster than a spike that is done on the ground. I will answer this by spiking the volleyball ten times, five times in the air and five times from the ground. I will be ten feet away from the wall and I am going to measure how high it bounces after it touches the ground. I chose this topic because I love volleyball and I wanted to know which position has more force and power. My hypothesis is “If an off the ground spike is made,…

There are so many kinds of throws in ball sports. For my science project I need to know about them so I have backup for my Hypothesis. I am testing whether a basketball goes farther using a chest pass, a push pass, an overhead pass or an underhead pass. The overhead pass has that extra flick of the wrist when your two arms are above your head. When you stop the motion to release the ball it gives a jolt to propel the ball forward.(Sarah Berton's brain). According to one source I read, this…

Conclusion The initial hypothesis was rejected. The hypothesis was if the mass of the baseball bat affects the distance the baseball will go, then the heavier the bat is, the further it will travel. The average for the 283.5 gram bat was 49.2 meters. The average distance for the 396.9 gram bat was 52.29 meters. The average distance for the 595.34 gram bat was 50.84 meters. The average distance for the 708.7 gram bat was 45.5 meters. The results mean that the heavier the bat, the less distance…

for his great work was Isaac Newton. Newton is credited and considered as one of the most intelligent minds of the 17th century. He has made a big contribution to the scientific revolution, by developing theories on Calculus, Light, and Celestial mechanics. Newton also made many big discoveries that have changed the world and how we see it. Born into a farmer’s family on January 4, 1643 in Woolsthorpe, Lincolnshire, England is where Isaac Newton spent his early years. Being his father’s only…

Last Thursday, I had a hockey practice, and before anyone else came on the ice, my brother Michael and I were just shooting around. To see how fast my slapshot is, I had him stand at the other end of the ice, and using his phone, see how long it took for my shot to go from one goal line to the other, exactly 60.96 meters. Keeping the puck on the ice the whole time during my shot, changing just the position of the puck, my slapshot took 4 seconds to cross the far goal line, making my slapshot…
