Motion And Energy により Mind Map: Motion And Energy

1. Gravity and Periodic Motion

1.1. Gravity battery used as an alternative storage in storing a hydroelectrical to power a house.

1.1.1. A gravity battery is a type of electrical storage device that stores gravitational energy, the energy stored in an object resulting from a change in height due to gravity, also called potential energy. It is used to store energy in wind turbines and it is also long-lasting storage energy if we compare it to existing energy storage systems that are currently very costly. The ramp rate for Energy Vault's gravity storage solution is as little as one millisecond, and the storage system can go from zero to 100% power in no more than 2.9 seconds. Gravity Battery can also be used to store energy through solar energy from solar panels. In this technology, We can store solar energy through gravity battery that is convenient and long-lasting that can power up your house for 6-14 hours without the actual electrical energy that comes from wires.

2. Mechanical Waves and Sounds

2.1. Guitar

2.1.1. A mechanical wave is a form of matter fluctuation that permits energy to be transported across a medium. It requires a matter in order to transport their energy from one location to another. A good example of this is a guitar. A guitar relies on the vibrations with different various frequencies from the strings for it to produce sounds of different keys. Energy is released when the guitar strings are pulled, which travels through the medium in a mechanical wave. The sound is produced as a result of the disturbance in matter. If mechanical waves aren't present, vibrations from the bridge won't be transmitted and resonate throughout the top of the guitar.

3. Fluid Mechanics

3.1. Rocket Engines

3.1.1. Fluid mechanics is a branch of science that deals with the study of fluids, these include different liquids and gases, in a state of rest or motion, is an important subject in civil, mechanical, chemical, and sometimes even in aeronautical engineering. Nowadays, computational fluid dynamics has been widely applied for resolving different fluid mechanics problems in aerospace, automobile, heat, ventilation, and air-conditioning, oil and gas industry, manufacturing processes, and hydrodynamics. Factors also include fluid statics, fluid kinematics, and fluid dynamics. Why do people study fluid mechanics? There are a number of fluids that when burnt, produce lots of heat, which can be used for various applications, these includes petrol and diesel for vehicles, jet fuels for aircraft. There are some fluids like oil that have a tendency to exert very high pressure or force, these fluids can be used for lifting various heavy loads. These fluids are used in hydraulic machines and hydraulic lifters. Some fluids have excellent flow properties which can be used for the lubrication of various machines. Fluids like water possess kinetic and potential energy, which is used for generation of electricity as in hydroelectric power plants. Fluid mechanics helps us understand the behavior of fluid under various forces and at different atmospheric conditions, and to select the proper fluid for various applications. A sample example of fluid mechanics is rocket engines, a rocket engine is a reaction engine that can be used for spacecraft propulsion as well as terrestrial uses, such as missiles. Rocket engines take their reaction mass from within the vehicle and form it into a high speed jet, obtaining thrust in accordance with Newton's third law, these is cause by the role of fluid mechanics, in the rocket, the gas which accelerates, or the fluid working, comes from the hot exhaust produced during combustion, in a liquid rocket, the propellants, the fuel and the oxidizer, are stored separately as the liquids that work are pumped into the combustion chamber where the burning occurs.

4. Temperature and Heat

4.1. Oven Stordy

4.1.1. Compared to the other normal ovens, oven stordy can stored its temperature inside between 3-5 days. On the other hand, temperature is defined as the quantity measured by a thermometer, It is proportional to the average kinetic energy of atoms and molecules in a system. Heat describes the transfer of thermal energy between molecules within a system, that is caused by a temperature difference, and it can change the temperature of an object. That process can be seen through the used of this oven, either through radiation/conduction. The hot air flows by natural or forced convection while heat is distributed from the heating element by radiation. Moreover, the heat can be also transfer by conduction from the baking metal containers to the baked products. Conduction transfers the heat using direct contact; food is heated directly in a metal pan, in a liquid, or surrounded by air. Cooking of food usually uses a combination of these methods. Thus, without heat or change of temperature, transferring of heat will be impossible, specifically conduction. As a result, we can't cook/preheat a food without the help of conduction process.

5. Rotational equilibrium and Rational dynamics

5.1. Crank Powerbank x2

5.1.1. A crank power bank is a device that generates power by cracking a lever attached to it. The slider-crank mechanism is a four-bar linkage design that allows for both linear and rotary motion at the same time. The linear motion of the piston is transferred to rotational motion at the crank via a mutual link known as the connecting rod. Shaking forces are generated and applied to the crank's housing as the shape of the crank causes the conversion of linear motion to rotational motion. These shaking forces cause vibrations that hamper engine functioning. Furthermore, the process of physically turning the crank on the side of the charger generates the current required to power compatible devices. While these have two cranking points, by tying it to a stable base, the user can exert both sides, producing twice the energy.

6. Ideal gases and the laws of thermodynamics

6.1. Multifaceted Air Bag

6.1.1. A multifaceted airbag is an airbag that is installed not only inside the car but also on the front and back bumpers, as well as side by side, to protect not only the automobile but also the harm it may do. The Multifaceted Airbags contain a crash sensor that releases oxygen gas instead of nitrogen to fill the air inside the bags. Airbags are well-known life-savers in car crashes. The airbag is only supposed to deploy in moderate to severe frontal collisions. Airbags are often designed to provide additional protection to people who are already confined by a seatbelt. The majority of the designs are pyrotechnic in nature and can only be used once. The laws of thermodynamics are shown when a certain object transforms its energy from one thing to another. A great example of it is a crashing car where energy is transferred from the vehicle to anything it collides with, whether another vehicle or a stationary object, during an automobile accident. This energy transfer, which is affected by variables that change states of motion, can result in injuries and damage to vehicles and property.
