Introduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.
For this examination, the continued context of a simulation will be used. In function one, the relevant domain is from 0 seconds to approximately 2.165 seconds. Negative values in the context of a projectile make no sense, as it suggests negative time. Going beyond 2.165 seconds is also nonsensical, as it suggests the projectile is driving into the ground.
Physics was observed during a DHS girls lacrosse game by Newton’s Laws and in free-fall. Newton’s Laws consist of 3 different laws, the law of inertia, F=ma, and action-reaction forces. Free-fall was observed in the game when the lacrosse ball falls, and only gravity acts upon it. All in all, Newton’s Laws and free-fall was portrayed during the lacrosse game.
In the distances vs. time graph for slow constant velocity buggy vs. faster constant velocity buggy, both data represent similar linear lines. For instances both buggy start picking up distances at 0.6 seconds and then from there both buggy continue to cover more distance at different pace as time continue. Not onces, did either buggy stop or loses distances which help create the linear line. The differences between the two linear line is that the faster constant velocity buggy has a steeper slope than the slower constant velocity buggy. This mean that the faster constant speed velocity covers more distances compare to the slower constant speed velocity at the same amount of time.
Summary of “Forces on a baseball” by NASA.gov The article, “Forces on a baseball,” by NASA.gov, presents the facts on what makes a baseball fly threw the air a baseball. NASA.gov presents readers with the facts and breakdown drag,lift and weight, while explaining the air and temperature can affect how high and far the ball goes. The article references Newton’s first law of motion, “According to Newton's first law of motion, a moving baseball will keep moving in a straight line unless it is affected by another force.” As the article concludes, the author highlights that if the ball is perfectly round and smooth, its center of pressure will be exactly in the middle point.
In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.
Flying Footballs! Which size football can fly through the air the farthest distance? If the size of the ball does affect the distance traveled, then the smallest ball should travel the greatest distance, according to the hypothesis. In conducting the experiment, the procedures followed were; 1.
In the “Blast Off” lab, we had launched a foam rocket into the air by pumping air into a nozzle, shooting the rocket up, and then recording the time from launch to when it hit the ground. I have learned and now understand the mechanics of kinetic and potential energy. The experiment I had conducted relates to energy in that as we observed the rocket, its energy was constantly transforming as it was in motion. Kinetic energy is an object’s energy based on its motion. Potential energy is energy based on an object’s shape or position.
When the ball hits the ground its kinetic energy is turned into elastic energy this makes the ball flatten out. Then that elastic energy is converted right back into kinetic energy when it goes up. So the more kinetic energy a ball gets when it is dropped the more energy it will have when it hits the ground which will give it more energy when it is headed back up therefore making it bounce higher.
The main three types of energy that are involved are kinetic, elastic, and gravitational. Kinetic energy is naturally different for racquetballs and tennis balls because tennis balls weigh more. When measuring kinetic energy the mass of the object is used so tennis balls have a natural advantage to have a bigger kinetic energy. Even if the racquetball was traveling a little faster there is a chance that the tennis ball would still have a bigger kinetic energy. With elastic energy, both of these balls have it and so does almost every other ball in sports.
The ball will travel farthest if it is not popped up or
First, when the golf club is to hit the golf ball, all energy is stored as gravitational potential energy of golf club(Ep), so the total energy system before the golf club hits the ball is written as: ET = Ep(initial) = mgh As the club swings down, the gravitational potential energy is converted to the kinetic energy. And then when the club hits a golf ball, kintic energy of the club will be converted to the linear and rotational kinetic energy of the ball and some will be converted to heat and sound energy due to inelastic collision. In order to measure the gravitational potential energy, a golf club fell from the same height and the height reached after the collision was measured. The height difference between after the collision and before
As the marble slides down the first drop it will lose much of its potential energy corresponding to the loss of height. The marble subsequently gains kinetic energy – kinetic energy is contingent to the mass and the velocity of an object. The marble speeds up as it loses height, consequently, their potential energy is transformed into kinetic energy. Newton’s Second Law states that an object’s net external force is equal to its mass times its acceleration; simply, the acceleration is proportional to the force applied and also the mass of the object.
In a projectile, the only force is gravity, thus resulting in a downward acceleration. Gravity does not act in the horizontal direction, so the ping pong ball will theoretically travel at the constant horizontal velocity according to the law of inertia. Communally characters of ping pong balls and the nature of projectile motion will have important effects on the launcher that must be considered to ensure that the launcher fulfils the expectations
Physics Applied to Soccer Soccer. The most popular game in the world, and yet the most beautiful. This sport is known for its skill and its way of bringing people together. Though what most don’t know is that a great amount of physics can be applied to the game of futbol. From Newton’s Laws of Motion, to things such as friction and inertia, there is so much to learn from this sport.
