How does Physics relate to what interests me...

  1. Physics and Soccer

    physics relates to soccer because the movement of the ball through the air is in affect by the initial forces applied to it by the head or the foot. when it is in the air, gravity and aerodynamic forces can cause the ball to curve. When a ball is kicked it goes the same way as the airflow it reduces the pressure from the ball and it starts to spin. It is also in the running because in soccer you have to do alot of running.

  2. Mechanics is the main branch of physics pertaining to football. Mechanics is "the study of motion and its causes." When a football is thrown, it follows a parabolic curve because gravity influences the vertical direction it travels. As the ball is traveling up, gravity will take its force and slow it down. When the ball reaches it peak, it stop for a very brief moment. After its peak, the ball will keep accelerating due to the forces of gravity. The path of the football can also be called projectile motion. When players line up away from the line of scrimmage, they are ready to accelerate from a rested state to a high speed state. Being away from the line of scrimmage gives them more time to reach a high speed. When a player tries to change directions, they plant their foot in the ground. When they plan their foot, they apply force to the field. This applied force allows them to stop their motion and accelerate upfield. These concepts of physics show that physics is an instrumental part of football.

  3. Several aspects of volleyball defense involve physics, including displacement, velocity, and force. Each of the six players on the court is assigned to a certain position such as front right, front left, or back middle. Although the six players have a set spot, they move and adjust to the play of the ball, and the distance they move is considered their displacement. Displacment is defined as a change in position of an object and can be either positive or negative depending on the starting point and which direction is considered a positive move.

  4. Physics relate to my hobby basketball because when shooting a free throw, it isn't as simple as it seems. In physics it requires momentum, gravity and the projectile that is being thrown in a certain angle. Parabolic shape is comparable to an arc, which is why shooting is relied on it. Gravity pulls an object 9.8m/s² downwards, this is why if you were to shoot a basketball directly at the rim the gravity will pull it 9.8m/s² downward before it will go in. Furthermore, this is why it is necessary for the ball to be pushed up and outward towards the net, as opposed to just being pushed forward.

  5. Physics relates to softball by the gravity, speed, and forces against a fast pitch. All pitches have an arc because, gravity pulls the ball down no matter how fast the ball is thrown. The curved path that the ball takes is called a "parabolic arc". The height of this arc depends on: (1) the speed (velocity) that the ball is thrown, (2) the distance that the ball will travel, (3) the angle at which the ball is release, and (4) wind resistance.
    With all these factors, no pitch can be exactly the same.

    Physics also relates to softball when batting. When you hit the ball there are many reasons why it goes to a certain spot on the field. When the ball hits the bat there is a huge force upon a ball that was just going in the opposite direction. When it is hit far and high gravity is pulling it down at an equal pace as long as there is no forces disturbing it like wind.

    Physics and plane

    Physics relates with planes because allowing flight passes at slower speeds and lower altitudes above the icy terrain. The meridian would collect data on ice sheets using radar that send energy signal through several kilometers of ice and measures the reflection and vibration.

  7. When a stationary object is hit with force it moves changes its velocity, just like in a billards game of pool.At first the white key ball is at rest, but then the outside force of the pool stick causes it to move, this is called contact force. The gravity forces the ball to fall in the pocket, stops the velocity of the ball at rest.

  8. In this video reggie bush uses speed and momentum to be able to score a touchdown. When he cuts his speed slows down, following that his speed increases so he wont get taken down. With the speed he builds up his momentum so he is able to fly over the defenders and score.

  9. Baseball is used in physics because of Newtons second law states that an object will move with constant velocity until a force is exerted on it. So like when the pitcher throws it and the batter hits it. The bat has equal velocity of the ball to change directions and go the opposite way. It also depends on the mass of the ball and how fast the speed of the ball changes. Also the batter wants to hit the ball in the sweet spot of the bat so that there is less vibration and more force. Rather than hitting it at the end or the beginning of the bat were there is a lot of vibration and there is less force in it. So it wont travel at a high velocity because of the vibration and waves from hitting it in the wrong spot.

  11. Physics relates to me by swimming. Sir Isaac Newton developed three laws which can be used to describe swimming. The first law explains why it takes extra force to get moving or to stop moving through two different forces. Newtons second law explains why some people can swim faster than others. For example, if two people have the same mass and pushed off a wall and did not take any strokes, the person who used the most force pushing off the wall goes farther. Newtons third law is for every action there is an equal and opposite reaction. For example, when you pull the water down on your side using the breast stroke, the water moves down towards your feet while you are propelled forward. Action in this case would be you moving your arm in the water, and equal reaction is the water pushing back on you. Opposite reaction is the reason that forward movement occurs.

  12. Physics relates to soccer in so many ways. Its is relate because of Magnus effect. One way is a ball that is spinning about an axis perpendicular to the flow of air across it. When the air travels faster relative to the center of the ball where the periphery of the ball is moving in the same direction as the airflow. Also when you curve the ball you are making a Magnus effect.This causes the applied force to act as a torque, which gives the ball a spin, enabling the Magnus effect to come into play. You can go to this website to know more about it.

  13. Physics & Music


    Physics relates to music because sound is the medium of music, most of the physics of music is the physics of sound. Vibration is the source of all sounds. Vibrating objects push against the air around them, creation little zones of compressed air. The zone of compressed air pushes against the air around it, which pushes against the air around that, and so on. Between compression pulses the air springs out past the pressure where it all began, creating a zone of less pressure, or rarefaction. You end up with zones of compression and rarefaction that travels outward from the sound source, one after another at a rate equal to the rate of the source vibration and that is a sound wave. A sound wave have frequency and wavelength.

  14. I think Physics relates to my interest swimming is a physical activity. It has to do with Newton's Laws of Motion.

  15. Physics is related to me because cheerleading involves momentum which uses a gravitational pull whenusing a stunt group to lift someone which is shown in this video:
