Electricity is all around us powering technology like our cell phones, computers, lights, soldering irons, and air conditioners. It’s tough to escape it in our modern world. Even when you try to escape electricity, it’s still at work throughout nature, from the lightning in a thunderstorm to the synapses inside our body.

Heat that is transferred from one body to another as the result of a difference in temperature. If two bodies at different temperatures are brought together, energy is transferred, heat flows from the hotter body to the colder. The effect of this transfer of energy usually, but not always, is an increase in the temperature of the colder body and a decrease in the temperature of the hotter body.

There are two types of energy. Kinetic enerygy and Potential energy. Kinetic energy is also called energy in motion. Potential energy is possessed by bodies in motion. When a basketball is thrown, energy is supplied to the ball causing it to go in the air. When the basketball reaches its highest point, all its kinetic energy is stored as gravitational energy. Potential energy is also called the stored energy. It is performed when its is associated with forces thag depends on the position of an object. When the object is higher, the more stored energy it has, when it is in the lower position, it has lower potential energy

When you walk up a flight of stairs, you do work beacuse you are lifting youre body up the stairs. You do the same anount of work wether you walk or run. When you go up the stairs fast, you spend or consume more power in a shorter time than going slow. Power is measures in Joules per second (J/s) or watts (W).

A boy is lifting up a bag from the table does work. Why do you think so? Work is done by the boy as he lifts the bag beacause the component of the force exerted on the bag id parallel to the displacement or speed and direction.

Soun waves can only move through matter, solids, liquids, and gas. This is one of the many reasons why you can hear different sounds. The speed of sound waves does not depend on the source, but on the medium through which they move. There are several factors that affect the speed of sound as it travels in a medium to another. It affects the density, elasticity, and the temperature of the medium. What is density? Density is the compactness of an object. The speed of sound is also affected by air density. Air molecules at higher altitudes are much farther apart. What is a elasticity? Elasticity the ability of an object or material to resume its normal shape after being stretched.

There are seven colors. White light is made up of all these colors. Each color of the light bends to a different extent when it enters a prism. Red is bent the least, and violet is bent the most, beacuse it has the longest wavelength and have the lowest frequency. The process of seperating of colors is called DISPERSION.

Good Day! I am Kenjie Yuan V. Schwarzkopf from 8- Caraballo. Today we are going to perform a circular motion. What is a circular motion? circular motion is a movement of an object along the circumference of a circle or roatation along a circular path. There are two forces in circular motion. Centripetal force and Centrifugal force. What is the Difference from them two? Centripetal force is an inward force while Centrifugal force is an outward force. Earlier we had our example for circular motion. We have a yarn cd case with bowl. Inside the bowl is filled with water. After putting water. Our classmates and teacher tested if the water will spill or not. In this case, the water did not fall from the bowl. How did that happen? It is because the centripetal causes the water to be pulled inwards. In other terms, into the bowl causing it to not fall. And the force was the first one to do a circular motion that is why the water did not spill. Thank you for reading my another blog!

Last week, we did another experiment. It is about action reaction. It is an interaction between two objects that have made contact with each other. The experiment that we did is a marble action reaction. We have 4 marbles in all, and the 3 marbles are in a same line. The fourth marble is away. The fourth marble with do the reaction beacause it is the one that do to make a reaction. The reaction was performed when the fourth marble touch the other marble. When the reaction was performed, the it touches the other marbles that made the marbles move.

Ika 22 ng agosto 2019, Huwebes. Kami ay nagsagawa ng isa nanamang aktibidad tungkol sa akselerasyon. Ang mga materyales ay Sasakyan na gawa sa papel, plastic straw, 25 centavo coins, at ang pambomba o ang buga ng hininga. Ang kailangan gawin ay obserbahan ang sasakyan na walang laman na coins at meron. Titignan dito kung gaano kalayo ang mararating ng sasakyan na walang laman at may laman. Nang matapos kami sa eksperimento, kinuha namin ang average ng bawat sasakyan na may ibat ibang dami ng centaco coins. At ng makuha namin ang average. gumawa kami ng graph para malaman ang mga bilis ng bawat sasakyan. At ng makita namin ito, hindi ito nagawa ng ayos. Hindi ito nagawa ng ayos dahil sa mga maling pagkakagawa ng ekperimento o aktibidad: ang hindi constant na pagbuga, maling pagsukat sa mga straw, at marami pang iba. So, paano nga ba nagana o nalalaman na may akselerasyon ang isang bagay? Ang akselerasyon ay kapag mataas ang force, mataas ang akselerasyon. Kapag mababa naman ang force, mababa din ang akselerasyon. Kapag mataas naman ang mass, mataas din ang akselerasyon. At kapag mababa naman ang mass, mataas naman ang akselerasyon.
