Hi I'm Brittney and i'm new, i help on a physics project

In summary, the contestant must make a design that will stop the egg from breaking when it is dropped from a height of 8 meters. The contestant must also make sure the design is lightweight and fast.

Hi I'm Brittney and I'm new, i need help help on a physics project! :)

Hi, I'm new on the forum. I have a physics project and i figured that someone could help me on my design. we are doing an egg drop competition i will start off by showing you the rules and regulations..

Purpose:
The purpose of this contest is to design and build a container that will prevent a fresh raw egg from breaking or cracking when it is dropped from a height of 8 m (26 ft). The winner will be determined based on the following criteria:

1. Egg does not break
2. Fastest fall time
3. Lightest container

A. Weight of container:__________g
B. Time for fall:_____s
**Mass + (10 x time) = _______
** lowest number is winner. If your egg breaks you will be disqualified.

Rules:
1. All containers must fit into a cube with inside dimensions of 30.0 cm x 30.0 cm x 30.0 cm.
2. The container may not change shape or size during the fall.
3. One raw white grade A large egg will be given to each contestant the day of the competition. contestants may not use their own eggs.
4. All containers shall be loaded by the contestants and dropped by the instructor. Containers must be labeled with your name and a mark indicating the top.
5. The dropped container shall be opened by the contestant in the presence of the instructor.

Restrictions:
1. No liquids or anything that will splatter
2. No high viscosity objects (ex:peanut butter, jelly etc.)
3. No sharp objects or hazardous materials
4. No mechanical power (ex: wind-up propeller)
5. Device or container must be homemade (ex: no airplane kits, nurf balls, etc)
6. weight of device or container (without egg) cannot exceed 200 grams

Any help with design ideas would be very much appreciated.
I was thinking something with bubble wrap or Styrofoam, but I'm not sure how to keep the egg in place or even how to put the bubble wrap. I'm not really good at physics, and i don't really have anyone to ask for ideas. Please help.

Brittney :)

In fairness we can't tell you what to do or how to build it, but there's dozens of ways to do it successfully anyways

First make sure you understand the problem. If you drop an egg WHY does the egg break when it hits the ground? This sounds simple, but it's because it stops. If you try to catch an egg that someone drops, what would you do to not break it instinctively? You'd slow down how long it takes you to stop it, by moving your hands with it and gently slowing it to a stop. The faster it stops, the more force is being applied

So the three things you can do
A)Slow the overall speed of the container so it's just not going very fast (this never works in these things, and the rules prohibit the necessary things like parachutes)

B)Don't let it stop at all! Unfortunately gravity DOES exist and this isn't so much an option

C)Make the container stop it slowly

You've got the right idea with things like bubble wrap and styrofoam, the big mistake people make is trying to make a really rigid container that doesn't break. Well if you're driving a car made of iron that rams a wall going 50 mph, that doesn't really do you any good at all, does it? In fact it would do you a lot worse. So you want the container to give and break and crumple or whatever, to slow the deceleration

Okay i see where you are coming from, but how could i slow the fall, my grade is based on a fast drop.
 
  • #4
Well like I said you're not going to really be able to do that

I wouldn't even worry about speed and weight yet, first make a design that actually keeps the egg alive.

I was thinking i could either use like two sponges and wrap them around the egg holding them together by a rubber band. or i could do something with marshmallows...
 
  • #6
Marshmallows is a neat idea...if you get something like that that works it's probably going to fall slow (but doesn't everything accelerate at 9.8 m/s^2 on earth? Well...in a vacuum. We're definitely not in a vacuum)

If it survives impact with the ground it should survive being put on top of a small weight, and you can experiment to find out what works best(because if you add mass, it'll fall faster, but weigh more, so you can figure out the optimal combination)

What is the physics project about?

The physics project is about investigating the relationship between mass, force, and acceleration. We will be conducting experiments and analyzing data to understand the principles of Newton's Laws of Motion.

Can you explain Newton's Laws of Motion?

Newton's Laws of Motion are three physical laws that describe the relationship between an object's mass, its acceleration, and the forces acting upon it. The first law states that an object at rest will stay at rest and an object in motion will stay in motion with a constant velocity unless acted upon by an external force. The second law states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. The third law states that for every action, there is an equal and opposite reaction.

What experiments will you be conducting for this project?

We will be conducting experiments involving objects of different masses, forces, and accelerations. Some examples of experiments include measuring the acceleration of a falling object, determining the relationship between force and acceleration, and investigating the effect of mass on an object's acceleration.

How can I help with the project?

As a new member of our team, you can help by actively participating in the experiments, collecting and recording data, and contributing to the analysis and interpretation of results. Your fresh perspective and ideas will also be valuable in the project.

What is the expected outcome of this project?

The expected outcome of this project is to gain a better understanding of the principles of Newton's Laws of Motion and their application in real-world situations. We also hope to improve our critical thinking, data analysis, and teamwork skills through this project.
