Motion of the Ocean

   Hey guys, I'm back with another post! This week, we will be discussing motion, and the different types of motion!

   First and foremost, you need to know that all matter in the universe is in motion: blood circulating through your body, trees swaying in a breeze, the Earth revolving around the Sun, the moon around the Earth, and so on. You must first recognize that an object has to be in motion so you can describe the motion. Next comes relative motion. Relative motion is the calculation of a moving object with regards to a different moving object. For example, let's say that you are on a train and you look out the window. You will notice that everything around you is moving, or so you may think. In reality, the only thing that is moving is the train.

   The next thing you need to know is distance and displacement. Distance refers to how much ground an object covers during its motion, whereas displacement is the objects overall change in position. So, let's say that a baseball player hits a home run, and each base is 90 meters apart. If the player runs to all the bases and makes it back to home plate, they have traveled a total of 360 meters, which is there distance. The displacement, however, is 0 meters. Why, you ask? Well, it's because the player didn't change positions; they started at home plate, and they also ended there. Make sense?

   Now comes speed, which refers to how quickly an object is moving. It is calculated by using the formula speed= distance/time(s= d/t). Now, I know what you're probably thinking right now: Why are you telling me the definition of speed? Everyone knows what speed is. But you may not know the different types of speed, which are average and instantaneous speed. Instantaneous speed is the speed of an object at any given instant. Average speed is the average of all instantaneous speed. Say you're walking down the street, and your average speed is 3 meters per second. If you broke into a run, which added up to about 8 m/s, and ran a total of 16 meters, then went back to walking 3 m/s, the running would be your instantaneous speed. Yeah, I know, it's a bit confusing, but you'll get the hang of it.

   The final thing I will teach you is velocity, which includes the distance/time ratio, but you also need to include the direction in which the object is travelling. So instead of saying that an object is moving 49 miles per hour, you have to say that the object is moving 49 miles per hour west. The formula for velocity is velocity= distance/time(v=d/t).

Well, that's all for today, folks! Hope everyone was able to learn
