Fluid mechanics

For task one My hypothesis was "If the forces on each side of the rope are equal, then the sum of forces will be zero. If we can determine the force each person on both sides of the rope, then we can determine if the sum of their forces will equal zero. " which was, correct. I know my hypothesis was correct because of the balanced force. A balanced force is when you have an equal amount of force on each side of an object when force is being exerted on it, it doesn't move because there is no…

photon is typically seen as a particle or wave representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass. Photons are currently best explained by quantum mechanics. However, it is important to know that photons have both the qualities of waves and particles which is known as wave-particle duality. As Einstein once said in attempt to explain wave-particle duality, "It seems as though we must use…

Learning Experience number ( 2 ) 1- Arnold Dumbbell Press - raising the dumbbells as i rotate the palms of my hands , is the concentric motion. The second phase, as I lower the dumbbells back down, is the eccentric motion, . as i pause while the the dumbbels are at the top, is the isometric contraction. 2- Alternate Hammer Curl - as I curl the weight toward my shoulders, is the concentric motion. as I lower the weight back down, is the eccentric,motion. As the weight is held at the top of the…

The purpose of the experiment was to determine how altering the amount of mass in a makeshift rocket will affect its distance. Our hypothesis stated that when more mass is added to the rocket, its distance will also increase. To investigate this theory, we conducted an experiment in which the mass of the rocket would be changed using differentiating amounts of water. To measure the height of the bottle rocket, we took rope and attached it to the girth of the liter bottle to determine how high…

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…

Niels Bohr was born on October 7, 1885 and died November 18, 1962. Bohr was one of the four outstanding scientist who helped construct the atom. Niels contributed to the atomic structure and quantum theory. He received the Nobel Prize in Physics in 1922 for his work. Bohr was a physicist, philosopher, and a promoter of scientific research. Bohr’s proposal stated that the electron revolve in a stable orbit around the nucleus and that the energy levels in which the electrons are on are discrete.…

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…
