What is Linear Motion?

Now, what is motion in a straight line? Objects move in motion, right? Those objects may move in 1 dimension, 2 dimensions or 3 dimensions. Today, we are going to discuss the motion of an object in 1 dimension. And that is the motion in a straight line. Motion in a straight line can also be called Linear Motion.

In Linear Motion, we will be talking about the position, displacement, velocity, and acceleration of an object.
Alright! Let’s start with Position.

The position of an object along a straight line can be uniquely identified by its distance from the origin. What does that mean? It means that the object only moves in one coordinate in the Cartesian plane which may go to the right or to the left of the 0.

The position of an object is relative to the reference frames. But what is a reference frame? A reference frame is an arbitrary set of axes from which the position and motion of an object are described. It means that it is where we base the motion of an object.

Take for example a rocket to be launched into outer space. Since the final destination of the rocket is in outer space, we can use the Earth as our reference frame. And from there, we can now calculate the position of the rocket with respect to Earth.

But not all reference frames are stationary in a linear motion. Sometimes, there are also moving reference frames that we can use in getting the position of an object in motion.

Enjoy this video about motion along a straight or in its other name which is the linear motion.

⁣Interdependence. All organisms in an ecosystem depend upon each other. If the population of one organism rises or falls, then this can affect the rest of the ecosystem. If the foxes in the food chain above were killed, the population of rabbits would increase because they are no longer prey to the foxes.

⁣A predator is an animal that hunts, kills and eats other animals for food. Prey are the animals that predators kill for food. In a food chain, if the population of prey increases, there will be more food available for the predator, which results in the population of the predator increasing.

In this basic accounting lesson, we share a tip on how to simply remember your debits and credits using the acronym "DEAD CLIC". Check it out, it should make it very easy for you to remember what to debit and what to credit. You will be able to apply it easily when doing your general journal or accounting equation.

⁣Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

⁣Perimeter is the distance around a two dimensional shape, a measurement of the distance around something; the length of the boundary.

⁣Every person has a blood type, (O, A, B, or AB) and an Rh factor, either positive or negative. The blood type and the Rh factor simply mean that a person's blood has certain specific characteristics. The blood type is found as proteins on red blood cells and in body fluids. The Rh factor is a protein that is found on the covering of the red blood cells. If the Rh factor protein is present on the cells, the person is Rh-positive. If there is no Rh factor protein, the person is Rh- negative.
The following are the possible combinations of blood types with the Rh factors:
Rh Positive Blood Types:
A+, B+, 0+ and AB+
Rh Negative Blood Types:
A-, B-, 0- and AB-
Rh factors are genetically determined. A baby may have the blood type and Rh factor of either parent, or a combination of both parents. Rh factors follow a common pattern of genetic inheritance. The Rh-positive gene is dominant (stronger) and even when paired with an Rh-negative gene, the positive gene takes over.
If a person has the genes + +, the Rh factor in the blood will be positive.
If a person has the genes + -, the Rh factor will also be positive.
If a person has the genes - -, the Rh factor will be negative.

⁣So how can we understand this magical process called the water cycle? There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam.

What is Homeostasis? | Physiology | Biology | FuseSchool

Homeostasis is a term first defined by Claude Bernard in 1865. It means maintaining a constant internal environment.

Senses all around the body are measuring various things and sending the information back to the brain. The brain then does its best to keep all these things stable and constant to keep the body working properly. Homeostasis is maintaining a constant internal environment.

What kind of things need to be kept constant in the body? It's very important to keep our temperature the same, at around thirty seven degrees Celsius. You can find out more about this in the video on temperature regulation. You also need to keep the levels of sugar in the blood constant along with levels of ions and water. Your blood pressure needs to be carefully monitored along with the amount of waste in the blood such as carbon dioxide and urea.

Let's say one of these factors goes too high or low, what is the brain going to do to get it back to normal levels? The answer to that is negative feedback. Negative feedback is the process whether the brain uses either a hormone or the nervous system to send a signal to the part of the body that can rectify the problem. For example, after you eat a meal with your blood sugar level increases. This is detected, and the pancreas will release a hormone called insulin that causes the sugar to be stored in the liver. The blood sugar level will then return to normal.

Negative feedback is the leap from which the body takes a stimulus, reacts by responding accordingly and brings the body back to the normal levels.

So why is homeostasis so important? Our metabolism, which is all the chemical reactions in our bodies that keep us alive, is controlled by enzymes. These enzymes only work in very specific conditions. If these conditions change, they could stop working and we could die.

Luckily, all of this happens without you having to think about it. If you had to do it yourself, you would have to spend all day and night just trying to keep all these things constant and we'd have no time to doing fun like watch videos of cats on the Internet.

⁣The functioning of the water cycle involves a change in energy which leads to a difference in temperature. The carbon cycle is a biogeochemical cycle that facilitates the exchange of carbon through the different compartments of earth. Carbon is the backbone of all biological compounds and many minerals like limestone. ⁣The terrestrial carbon and water cycles are strongly coupled. As atmospheric carbon dioxide concentration increases, climate and the coupled hydrologic cycle are modified, thus altering the terrestrial water cycle and the availability of soil moisture necessary for plants' carbon dioxide uptake.
