Speedometer

The Big Picture

Our project is focused on the speedometer inside of your mobile devices. We will use it to measure your speed when driving and the frequency of hard stops.

Principles and Concepts

Our project covers the laws of inertia, torque, and Newton's first law as they are all very relevant to speed. If you haven't heard of these before or need a refresher, look below:

Inertia:

Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law of motion.

Torque:

In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force. It represents the capability of a force to produce change in the rotational motion of the body. The equations is as follows: T=rFsin0

Newton's First Law:

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

Keywords and Units:

There are going to be a lot of keywords and units of measure that will need keeping in mind, as this is a real life science focused project and just a videogame. They are listed below:

MPH:

MPH means Miles per Hour, and this is the standard unit of measurement of a vehicle's speed in the United States of America, AKA imperial system.

KMH:

KMH means Kilometers per Hour, and this is the standard unit of measurement of a vehicles speed in the rest of the world, AKA metric system.

M/S:

Meters per Second, this is the unit of measurement the speedometer uses in a average mobile device in the United States of America, and this will need to be converted to MPH later on for mass use by companies.
