Q3 VECTORS

TYPES OF ENERGY // 01

According to Physics there are nine types of Energy which make the universe we know, and there are; Atomic Energy, Thermal or Heat Energy, Light Energy, Sound Energy, Electrical Energy, GPE, KE, Chemical Energy, and Elastic Energy.

When talking about Energy we always have to have in mind the Law of Conservation of Energy, which states that Energy cannot be created or destroyed, it is only transfered from one place to another.

Let's TRANSFER ourselves to the next set of games!!

GRAVITATIONAL POTENTIAL ENERGY (GPE) & KINETIC ENERGY (KE) // 03

Gravitational Potential Energy (GPE and Kinetic Energy (KE) are bonding to each other as the YIn Yang: GPE depends on your position and the energy stored in you or the object due to the Gravity of our planet. The higher the object is, the greater this energy will be.

Kinetic Energy is also known as the energy of motion and it is proportionally related to the velocity of the object.

When and object changes form a rest position with a certain height to be in motion, it is swithing its GPE into KE.

Let's get Rolling wirh GPE & KE!!!

WORK & POWER // 05

In Physics, WORK happens when a force acts upon an object and causes its displacement. In other words, holding a 25 Litre Water bottle isn't consider as WORK, but moving the same bottle a certain distance is clearly considered WORK.

In addition, you can move that bottle slowly or fast which in terms of WORK will be exactly the same, but we know that the energy spent will be totally different, so this is where the term POWER comes in, which is defined as the amount of WORK per unit of time.

Work as energy is measured in Joules (J) and Power in watts (W=J/s).

Let's show our POWER !!!

VECTORS // 02

There are two ways we can represent a variable in Physics and it is using a Scalar or a Vector.

Scalars are just numbers that indicate the magnitude of the variable, for example; 25 liters of water, 30 years old, 450 cal.

Vectors in the other hand besides expressing Magnitude, they also show direction, for example; 25 m/s NE, 500 meters uphill, and they can be represented using an arrow.

They can be added using three methods; Parallelogram, Triangle (Heat to tail) and Polygon.

Enjoy the impact of the next games using VECTORS !!!

ELASTIC POTENTIAL ENERGY (EPE) // 06

It's incledible how some materials because of the elements and compounds they are made of and their molecules' structure 3D arragment, they have the capacity to strech and store energy at the same time that can be later on released becoming what we know as Elastic Potential Energy (EPE).

Slingshots, catapults, soccerballs, jumping stilts are a few examples of different things we use in our lives thanks to EPE. Scientists are discovering new materials (carbon based compounds) that can store better this type of energy and will help us to perform our everyday acitities.

Let's see how good we are with a sligshot or catapult, ENJOY !!!

MAGNETISM // 06

Strange and powerfull is Magnetism which affects particles as small as Quarts and Leptons but at the same time, it has an effect over the Cosmic Rays that will kill all living organisms on Earth by forming a shield around it.

There are different types of MAGNETISM, but in general we can split them in Ferromagnetism materials and Electromagnetism. The first are materials that can align there electrons easily causing MAGNETISM and they are; iron, Nickel, Cobal and Gadolinium. The second type is the MAGNETISM produced when electricity passes through a wire made of a metal, such as Copper and forms it.

Let's play with a little MAGNETISM !!!
