Project
For this project we were tasked with designing a 3D helmet. Before we could start this though, we had to learn how to use a modeling program. The on that we were assigned to use was Fusion 360. We were given a tutorial to help us model the helmet so that we could learn the basic steps to create one. After completing the tutorial, we then sketched out and researched designs for helmets. Now we could start to model our own helmet.

Key Concepts
ACCELERATION is a change in speed over a period of time; the higher the acceleration, the faster the change in speed. For example, if a car goes from 0 miles per hour (mph) to 60 mph in 2 seconds, it is a higher acceleration than if the car goes from 0 mph to 40 mph in 2 seconds. Acceleration is a rate of change of speed; NO change means NO acceleration. If something is moving at constant speed, it is NOT accelerating.
COEFFICIENT OF FRICTION is the measurement of the level of friction embodied in a particular material. The formula is μ = f/N, where μ is the coefficient of friction, f, is the amount of force that resists motion, and N is the normal force. Normal force is the force at which one surface is being pushed into another.
CRUMPLE ZONES are areas of an object designed to deform and crumple in an impact, as a means to absorb the energy of a collision. The fronts of most automobiles are designed as crumple zones to protect the passengers from frontal collisions.
DRAG is a term used in fluid dynamics that is sometimes referred to as air resistance or fluid resistance. Friction is one of multiple factors that influence the amount of drag encountered by a body moving through a fluid such as air or water.
INERTIA: when an object remains still or moves in a constant direction at a constant speed.
G FORCE: a force acting on a body as a result of acceleration or gravity, informally described in units of acceleration equal to one g.
FRICTION is a force that resists motion when two objects or surfaces come in contact.
FORCE causes masses to accelerate; they are influences that cause a change of movement, direction, or shape. When you press on an object, you are exerting a force on it. When a robot is accelerating, it does so because of the force its wheels exert on the floor. Force is measured in units such as pounds or newtons. For instance, the weight of an object is the force on the object due to gravity (accelerating the object towards the center of the earth).
KINETIC FRICTION (or dynamic friction) occurs when two objects are moving relative to each other and rub together (like a sled on the ground).

Reflection
During this project I learned the meaning of challenging again. Learning Fusion 360 proved to be no easy task. Some things I did well however even with these difficulties was designing the helmet, playing to my strengths. I was also able to delicate roles effectively since we were able to divide and conquer the research, sketches, and modeling.
There was room for improvement with this project. Once I realized that the tutorials were out of date, I should have tried to find newer versions and look further into the process instead of trying to just figure it out on my own. The computers we have access to at school also proved to be very poor. Due to this I should have worked and done the project at home and researched safety methods at school with my team. There are main problem solving lessons that I have learned from this project and I will try to use them to my advantage in the future.
