Essay about Chapter 1 Lab

In this series of experiments, we examined the back and forth motion. We analyzed the motion of five objects which included a mass attached at the end of a spring, a swinging pendulum, a ball thrown up in the air, a jumping student, and a cart rolling up and down an incline. Using the motion detector and a computer we were able to come up with graphs of position VS time and Velocity VS time from which it was possible to tell where the velocity or the acceleration were maximum, and whether they were changing or not. Besides that, the graphs also helped to notice objects that exhibited a similar type of motion.

The player has now compressed the spring in the ball shooter. The ball sitting in the ball shooter is at rest. It will be at rest until acted on by an unbalanced force. This is Newton’s first law of motion, the law of inertia (Kirkpatrick and Wheeler p31). The ball shooter is then released the spring decompresses and strikes the ball sending it up the incline to the top of the pinball playing field. The strike on the ball is called the impulse. The time interval it takes for the ball momentum to change. Since the ball has no momentum because it has zero velocity the ball shooter transfers its momentum at the impulse (The Ball Shooter 2003). This also takes place in the time frame of about a second.

C. Once the ball is hit you do not just stop as most beginners do, you want to follow through. According to…… a proper follow through will allow the ball to be hit straight instead of to the right or left.

In the tennis serve Newton’s third law of motion is applied as the player performs a leg drive to the court to generate an equal and opposite reaction (Ackland, Elliott & Bloomfield, 2009, pp 314).

Once accomplishing the motion of your hips, a player must focus on the next link in the chain, pulling the stick away from his body, preparing to move forward (accelerate) with a shot. A goalie uses his or her angle of perception to watch the ball and to make a save. The intent is to hide the head of the stick behind the player’s body to decrease the visibility of the ball to the goalie. The more a shooter hides the head of the stick the less likely the goalie with stop the ball from accelerating into the back of the net. When the act of pulling the stick takes place, a shift in weight occurs. “This shift in balance enables the player to release the ball while allowing his hips and back to recoil and urge the shoot motion in a forward direction. This forward acceleration causes an increase in the player’s velocity, zero to forward” (Russo, 1). Depending on the magnitude of your acceleration depends on how “hard or fast” the player pushes off the ground with their foot allowing them to make the initial forward progress. Without the push off the ground, no forward movement would be possible.

The fastest growing sport in America is lacrosse, and in order to play lacrosse, it is important to first understand the physics of the game. Lacrosse players around the world use physics while playing without even thinking about it. With no knowledge of physics, it would be pretty difficult to master the fastest game on two feet. One of the worlds greatest scientist, Isaac Newton, established three laws dealing with physics, and using these laws will make it possible for a lacrosse player to understand what he or she needs to do in order to throw a ball. Newtons first law deals with inertia, his second law deals with the relationship between mass, acceleration and force, and his third law deals with opposite reactions. When talking about lacrosse, it is essential to cover Newton’s first law, his second law, and his third law in order to understand the physics behind throwing a lacrosse ball. .

and the hand continues through its motion. Angles were placed on each still shot at the

The physics involved in soccer includes friction, torque, center of gravity, Magnus Effect and Newton’s three laws of motion. The physics of soccer comes from three main parts of physics which is velocity, acceleration, and displacement. Velocity is shown in soccer with the speed and direction of the soccer ball when it is hit or kicked. Acceleration is shown in soccer when the ball changes velocity when it is hit or kicked. Displacement is the change in position of the soccer ball.

2. The ball contains kinetic energy while in motion near the bottom of its path.

Vocabulary: acceleration, centripetal acceleration, centripetal force, Newton’s first law, Newton’s second law, uniform circular motion, vector, velocity

The relationship is I have to keep moving the ball so I have to keep measuring the ball. That is how they are related. Now I will discuss my experimental procedure. My procedure was this. First I needed to measure out my angles from the penalty dot. Then I needed to kick the balls into the goal and record my data out of five. Some of the things that may have affected my results were that it had snowed and I had to shovel part of the field, and it may have made my tired. Aklso that it was really cold and I may have been off my game because of

The task that will be performed in the lab is a football snap toward a target. The subject will face way from the target, place their feet about shoulder length apart, place the ball between their feet, bend over and snap the ball through their legs to hit the target. For the experiment, the target is a wall. The wall is marked in increments of 20cm; a center space with five spaces above and below.

In the picture below, How is the game played? A. Kicking a steel ball, B. Hitting a rubber ball with hips or C. Throwing a silicone ball. Answer = B

2. No, the forces went in equal and opposite directions just as the rubber band and string

back in a smooth motion and using force to release the ball (science has proven that force
