Egg Crash Lab Report
The purpose of the egg crash is to design, build, test, and evaluate a landing pad to protect an egg from the collision of a hard surface falling from various heights. An individual should be able to describe the collision in terms of changing momentum, impulse, impact force, and impact time. All moving objects have a quantity of motion, otherwise known as momentum. Momentum of a moving object can be found by multiplying the mass of the object by the velocity. Because mass is measured in kilograms and velocity is measured in meters per second, the unit for momentum is kilogram meters per second. Similar to velocity, acceleration, and force, momentum is also described by its direction along with its quantity. The momentum of an object will always be in the same direction of its velocity. Objects with a lot of momentum are hard to stop. Two football players of equal mass are traveling towards each other, one is moving at 6 meters per second, and the other is moving at 9 meters per second. The football player moving with the faster velocity (9 …show more content…
In a collision, a moving object experiences a force acting on it for a certain amount of time; this results in the change of momentum. The impulse can be found by the equation, Impulse=Force x Time. The most common use of impulse is used with the car airbag system. The airbags in cars work to reduce the damage to the people involved. The airbag works to increase the time needed to stop the momentum of the individual in the car. If the time is increased, the force of impact will decrease. Research shows that the mass of a car, rather than the size, is the leading factor in reducing the risk of fatality. In a report done testing this theory in 1992, Evans concludes, “Mass is the dominant causative factor in relationships between driver risk and car size in two-car crashes, with size, as such, playing at most a secondary role. Reducing car mass increases occupant risk” (Evans, 1992, p.

Broken Eggs POWBy: Faith LeonardThe problem is that a farmer is taking her eggs to the market in her cart. Along the way, she hits a pothole, which jars her cart and spills the eggs. The farmer is unhurt but every egg is broken. She goes to her insurance agent, who asks her how many eggs she had. She doesn’t know, but what she does remember some things from various ways she tried packing the eggs. She knows that when she put the eggs into groups of 2, groups of three, groups of 4, groups of 5, and groups of 6 she always had 1 egg left over. But when she tried putting them into groups on seven she ended up with no egg left over. What we did was find…

When assigned the project of creating a device to secure eggs in a collision with a pendulum at increasing velocities, I immediately thought of a car crash. Cars must be built that so that they will protect the passengers during any type of collision, like my project must be built to protect the eggs. Upon this thinking I decided to design my egg crash project like the design of a car. I would create an inelastic collision between the pendulum and project, meaning…

My name is Madison Johnson. I am in the 9th grade. I am in Mrs. Logan’s biology class. I am doing my project on “The Magic Floating Egg”. Eggs sink in normal tap water and I am testing whether or not changing the density of water will make the egg float. I was looking at projects on sciencebuddies.org and I saw that multiple people had done this. I am trying to prove that when you add a certain amount of salt to water, it will make it more dense. I took pictures of the results. This information can be useful because we can test the density of salt water versus the density of normal tap water..…

The core problem is that a typical car, weighing more than 4,000 lbs. driving 60 mph has a huge amount of momentum. If a car hits something at that speed, all of the momentum is stopped with a massive amount of force required because change in momentum equals force multiplied by time. All of that force is then transferred to the passenger. Adding in features that will make things crumple, such as plastic bumpers and shock absorbers, will reduce the amount…

The conservation of momentum can be a huge effect on the cars, so the conservation of momentum states that when there are no other outside forces like friction the total momentum of the objects interaction does not change. The amount of momentum before and after the collision will be the same. If this is the case then the momentum of the first car, mass times velocity, does not change the momentum of the second car if the second car is at rest so the second car would have the same momentum as the first…

What is momentum? Momentum is defined as mass in motion. You can calculate the momentum of an object by multiplying the mass of an object by its velocity. Newton’s first law applies to momentum. A moving object will stay in motion unless an outside source interferes with it, and this is the same with momentum. The momentum of an object will not change unless it is interfered by an outside object or force. An example of an object with a lot of momentum would be a bullet. This is because it is a small object with a lot of momentum, therefore, it is hard to stop…

If we a car with a mass of 1500kgs was driving at a velocity of 20ms-1, its momentum would be 30,000kgms-1. If we assume that this vehicle crashed into a solid concrete wall, with the time taken being 0.05s, we can calculate the force that the car exerts on the wall and the force the wall exerts on the car. All we need to do is rearrange the equation Impulse= Ft to F=Impulse/t. Because the impulse is the change in momentum (final-initial), the impulse would be 30,000kgms-1. 30,000/0.05 =…

Newton’s Third Law; the motion states that for every action there is a an equal and opposite reaction that acts with the same momentum and the opposite velocity. An example would be a suction cup and spring attached to it. Sticking the object to a window, having the spring be squeezed together. Eventually, depending on how powerful your suction cup is, the object would spring off…

The faster a car is going the more force it has, the more force it has the more impact it has in how bad the crash is. For car occupants in a crash with an impact speed of 80 km/h (≈ 50mph) the likelihood of death is 20 times what it would have been at an impact speed of 30 km/h (≈19 mph) (WHO). When the driver goes 10mph over the speed limit the collision energy is increased by 78% (Philadelphia).…
