I decided on design 2 for my egg container for its lack of simplicity compared to design 1, and the design seemed more likely to succeed than design 3. During the research process, I found that a bounce to the container would be useful, so I attempted to incorporate that factor into the design of the outer shell by picking a material that would allow for a bounce. I also added cushioning to the egg, as recommended during my research. However, a difficulty I met during the building process was my inability to acquire the right material I wanted for the outer shell of the container. As a side attempt, the rotor I built also didn't work, since the blades were too weak. I did have a practice drop with my final container prior to the official drop …show more content…
When in freefall, the only force acting on the egg is gravity. At the start of the egg drop, the egg is held at a height of approximately 3 meters. The egg gains potential energy as it gets higher from the ground, so the egg's position is a factor in the fall. When the egg is released, Newton's first law of motion can be used to explain why the egg falls. Newton's law of inertia states that objects at rest tend to stay at rest until acted upon by an unbalanced force. Initially at the start, the egg was at rest when held 3 meters above the ground, but once the egg was released, gravity acts on the egg as an unbalanced force. This causes the egg to fall downwards under the force of gravity. A force acting on an object with mass will cause the object to change its state of motion, as stated in Newton's second law of motion. This law states that the acceleration of an object depends on the net force acting on the object and the mass of the object (a = F/m). This means that an increase in the force applied or the mass of the overall contraption will result in a greater acceleration for the egg. A greater acceleration for the egg would cause a greater change and increase in the velocity at which the egg is traveling over time. The time is how long the egg has to accelerate in velocity or speed. However, slowing down the velocity of the falling egg and increasing the time it'll take for the egg to fall and impact the ground is also a method to protecting the egg. Knowing about the timing of the fall can help guide the designing process into building a contraption that'll increase surface area and air resistance to slow the velocity of the egg, which will extend the time the egg falls. By the time the egg reaches the ground, Newton's third law comes into play. The third law states that for every action, there is an equal and opposite reaction. When the
INVESTIGATION FOLLOWUP Procedure My science experiment was to test toilet paper, to find a good toilet paper brand to use. The goal was to find the toilet paper that broke apart the fastest in moving water, the toilet paper that held the most pennies when wet, and the toilet paper that held the most pennies when dry. For the deconstruction test, what toilet paper would break apart the fastest in moving water, I tested the toilet paper by placing a mixer in water and dropping a 2 by 2 inch piece of toilet paper in the spinning water. I repeated this twenty times for each brand of toilet paper.
For each of the condition, about 35 milkweed bug eggs will be placed in clear container (5”x7”x4”) with a fine netting between the lid of the container and the container walls. The netting prevents the milkweed bugs from escaping while allowing for air to come in. Each container
An object on earth can not truly free-fall on earth because air resistance can amongst all objects no matter how miniscule and if there is friction pushing a body or an object the opposite direction than the downward acceleration due to gravity, then it can not be free, not under the control of another, falling. Therefore, the size and shape can also be factors affect how an object falls which on Earth, can not truly
In the second portion of this experiment we will keep the temperature constant and divide the ½ tablet of Alka- Seltzer into 2 pieces ,3 pieces and an unbroken ½ tablet. It is my belief that Alka-Seltzer
The formula for the 2nd law of motion is F=ma. (studios). The 3rd law of motion says, “that for every action (force) there is an equal and opposite reaction (force).”
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.
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.
Where we had to make a shield around the egg to prevent it from cracking. As Adrianne and I did the project together I noticed how uninterested she was in the work. The project was a large part of our final grade and I was determined to get a high score, but apparently, she didn’t care much about what the final grade would be and did very little.
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.

Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.
Final Analysis Paper The egg experiment was a creative way to helping us learn more about the development of children. I really enjoyed this project. I was able to learn a lot and be creative all at once. My child was a girl and I named her Victoria Blake.
Think of it like this, adding salt to the water makes it like an ocean which is easier to float and swim in than just normal/ distilled water. This is because salt makes water denser. When salt water gets denser, the easier it would be for objects to float on it. My hypothesis was correct. The water did go inside the egg, but the ones with least salt increased the most, unless the egg was the smallest and it had enough space to take in a lot of extra water.
DESIGN PSOW Ajit Rajendran 13H To Determine the Time Taken for a muffin paper cup to reach the ground, while Changing the Height of each experiment Introduction: In this experiment the aim is to determine the time taken for an empty muffin paper cup to reach the ground, by changing the height the empty cup is dropped from. Both variable mentioned are going to measured (height and time taken), when conducting the experiment. In order to have a fair experiment, certain factors will be kept the same throughout the experiment: the same paper cup will be used, the dimensions of the paper cup will be constant (where external factors do not affect the shape), the method in which the paper cup will be dropped.
Internally fertilized eggs are deposited in gelatinous mass. The large, yolky egg of terrestrial snails are deposited in moist environments, such as leaf litter, and a calcareous shell may encapsulate them. In marine gastropods, spiral cleavage results in free swimming trochophore larva that develops into another free swimming larva with foot, eyes, tentacles, and shell called a veliger larva. Sometimes, the trocophore is suppressed, and the veliger is primary larva. Torsion occurs during the veliger stage, followed by settling and metamorphosis to the
