Air mass Essays

4.3.8 When a ball is pitched, it stay in motion until it either fall, or is acted on by another object such as the bat, or caught by a person. The pitch and speed depends on the mass of the ball. Although it should be the same size, practicing with different balls will affect the speed. During the process of pitching, this will have a reaction on the ball causing it to move from one point to another. 4.3.9 ANGULAR MOMENTUM = MOMENT OF INERTIA X ANGULAR VELOCITY The angular velocity is the axis,

The question is, how does a physical or chemical change affect the mass of a substance within a closed system? To respond to this question, my group did a lab to determine whether or not the mass would change or not. Our lab was to have a plastic bag containing baking soda, then add a cup of vinegar and a block of clay to the mix. We made sure to weight every element separately and then add them up for our total mass of 31 grams before the reaction. During the reaction, as soon as the vinegar was

The central purpose of this experiment was to determine the experimental empirical formula of an oxide of magnesium by performing a synthesis reaction. It was hypothesized that the formula that was derived from the recorded data would be identical to the theoretical empirical formula. After performing calculations with the data that had been collected within the duration of the experiment, it was deduced that the empirical formula of the product generated by the synthesis reaction was Mg5O6. Since

not going into the goal. 2. Sliding friction pushes against an object when that object that is moving but not leaving the ground. 3. The higher the air pressure, the higher the air resistance. After a soccer ball is kicked if you head the ball the pressure of the air in front of the ball increases, causing air resistance to rise. The change in air resistance causes the soccer ball to slow down. 4. To complete a perfect header, it depends on the motion of your head, the motion of the ball, and how

for investigation 3 would have all be of uniform 90 degrees, due to the curvature of the motion at the canter of mass, our angles increased with time. 4. If there were no external forces acting on the two pucks, their complex motion could be described as the combination of the uniform linear motion of the center of mass and a uniform circular motion of the pucks about the center of mass. Describe how well your results agree with this expectation, and explain any deviations that you observe from the

cents each—to produce. In this lab, we analyzed penny mass to determine patterns between the masses. We came up with 30 different pennies and split them into trials. We ]hypothesized that the more pennies that were added will create a greater volume. Material and Methods Lay out supplies Fill graduated cylinders to 20 mL each Weigh penny trials on weigh boats and balance First trial put 5 pennies in the

theorized by Newton in 1666, then formally published in his book Principia Mathematica Philosophiae Naturalis. The three laws are: objects will stay at rest or be moving unless acted upon by an unbalanced force, acceleration depends on an object’s mass and the force acted upon the object, and if one object exerts a force on another object then the second object exerts a force of equal strength in the opposite direction on the first object. The first law, which states that objects will stay in

the size of a parachute affect the falling rate and safety of an object? A parachute is a device used to slow down an object that is falling towards the ground. Without a parachute the gravity is more than air resistance. But as the parachute opens, the Air resistance increases. Now air resistance is more than gravity. Using a parachute is safer because instead of falling straight down at an extremely fast speed they would be used to slow one down, with a risk of fewer injuries. one would measure

of 0. Since grass is not frictionless, the ball at first slides over the field, then begins to pivot and, in the long run, begins moving without slipping. A soccer ball moves without slipping when its focal point of-mass pace rises to its precise velocity (around its focal point of mass). Alright, now assume you need to kick the ball so that it promptly begins moving without slipping. How? You would give the ball "topspin" by striking the ball a separation (s) over a nonexistent level line that goes

then take the modified gyrocopter longer to fall and hit the ground because it is lighter and has more air resistance. Air resistance is the friction of the air and the object have against each other therefore the lighter the object is the more air resistance there will be because it is falling slower. Therefore “Weights allow for different air resistances – the heavier the object, the less air resistance... This resistance change, via weight, will cause the gyrocopter to fall in correspondence to

also studied the relationship between force vectors, mass and acceleration. Gathering of data took place through the use of a force table and a PAScar track system. Questions & Answers 1.For both the 1st and 2nd labs, we had objects that were “falling” (a golf ball for lab 1 and the hanging mass for lab 2). Was the acceleration of both objects constant? An object in free fall has constant acceleration. Were the two objects (golf ball and hanging mass) in free fall? Explain why or why not. (2 points)

Title: Determine how mass affects the way an object is pulled by gravity Aim: To find out the effect of mass on the falling time of an object from a specific height. In this experiment we will be dropping three different balls with different masses from a specific height and recording the time it takes to hit the ground. Hypothesis: The ball that is heavier/has more mass will hit the ground faster than balls that are less heavy/have less mass. Materials: • One 1m ruler • Three different

most use was the second law, There were two parts of this experiment the 1st part was about comparing and calculating the accelerations and the theoretical percentage, so the 2nd part was to measure the forces on the bob and its spring and to take the mass of each one. Discussion: Physics of the Experiment: First of all, 1st step was using a machine that called the Atwood

trajectory of a projectile (which can be pretty much any physical object — a rock, a ball, etc.) as it moves through the air.” In other words, the science of projectile motion can be estimated by an equation that allows scientists to predict the length of the trajectory of an object when projected into the air. Therefore, projectile motion is basically the path an object travels through the air. When in flight, the object (in this case a ping-pong

Law of Conservation of Mass Experiment CER Question: Does a controlled (closed system) zip lock bag experiment demonstrate the Law of Conservation of Mass? Claim In our class we did an experiment where we put different known supstances into a ziplock bag and closed the bag, that way we could achieve a closed experiment and attemp to support The Law of Conservation of Mass. The Law of Conservation of Mass states that mass can neither be created nor destroyed in a closed system. According to my data

object times its mass. If an object is in motion it has momentum. When a player kicks a soccer ball he transfers momentum to the ball and whenever he receives the soccer ball he slows down the momentum of the ball with his feet. The Magnus effect is of importance to soccer players who want to bend the flight of a ball. It explains why a ball curves through the air when it is thrown, hit, or kicked at the same time it is given a spin. A soccer ball is a projectile that flies through the air because of the

the study of air movement together. It is a subfield of fluid dynamics and gas, and the term "drag" is often used to refer to the gas dynamics. The earliest records of the basic concepts of aerodynamics on the work of Aristotle and Archimedes in the third and second centuries BC, but the efforts to find a quantitative theory of airflow develop until the 18th century, beginning in 1726 was Isaac Newton as one of the first in modern aerodynamics mind when he developed a theory of air resistance, which

This scenario relates to Newton’s 1st law, because in the scenario Kiya fast pitched the softball to Cameron and she swings the bat and hits the ball. At first the ball wasn’t going anywhere because Kiya was holding it. It started moving when Kiya put force and speed against the ball to make it move. Newton’s first law states that an object at rest remains at rest and an object in motion remains in motion with the same speed and same direction unless an unbalanced force acts upon it. The object that

to find the spring constant from the tweaked equation mentioned before. Conclusion This experiment confirms the relationship of the spring constant between the objects when projected with a certain field of force. Even with their difference in mass, each ball showed similar results when launched with 620 ±80N proving that spring constant has a relationship between if experimented properly. The spring constant of the rubber band in the slingshot I used is on average 1408 ±192(N/m) when the force’s

The density of a medium is an example of an inertial property. The greater the inertia (i.e., mass density) of individual particles of the medium, the less responsive they will be to the interactions between neighboring particles and the slower that the wave will be. As stated above, sound waves travel faster in solids than they do in liquids than
