I bet you think when you stand still, that you are completely motionless right? Well you're wrong. Even when you aren't moving, you're moving. When you are moving, you're moving. No matter what you do, you will always be moving, period. Confused yet? No? Let me try again. Trees on Earth are moving, your school is moving, even the cement on the ground is moving! By now, dear viewer, I'm going to assume you are confused about my paragraph. This is good; we are making progress.
Even you don't have to dance with a cat to be in motion. That's just ridiculous.
But on a more serious note, motion is movement. It occurs when something changes position relativity to a reference point. See that girl up there? ^^^ Every time they move, they are showing you motion. In fact, even f you aren't moving, you're moving. Your blood is rushing through your veins, your cells are moving, your lungs are pumping oxygen and carbon dioxide through out your body, and your brain is constantly working... unless you're a zombie.. which would be creepy.
Next we have something equally important: relative motion.
Relative motion helps determine if something has changed its position. What would also help with that would be a point of reference. I guess we could use a human as an example. Not just any human though, let's use Harry Styles. If Harry stands by a door and doesn't move, then he takes a step to the left, he changed his position. I can tell he moved because he is no longer near the door. This makes the door my reference point.
Next, we talk about distance. No, that doesn't mean I'm talking to you about how much effort it takes to run a few miles (which is a lot). Distance is the entire length something has traveled to get from Point A to Point B. The next crucial traveling term is displacement. Displacement is the difference in position between an object's starting and ending points. Still hard to understand? Ok try this example. We're going to use Harry Styles again, so here we go. If Harry has to get from his house to the studio, he can't just walk through buildings and things to get directly to the building now can he? Nope. He would drive his car on roads to get to the studio. Let's say he plugs in his GPS and it tells him that the studio is 3.7 miles away. Well, that's not entirely true. The GPS told him the distance. The studio is actually 1.4 miles away, but he can't go in a straight line. Therefore, the 3.7 miles to the studio is the distance and the 1.4 miles is the displacement. Now if you zoned out and/or skipped my example at the words 'Harry Styles' then here's a picture.
Easier? Good :)
Next we have the discussion of speed. This can often be confused with velocity, but I'll explain that later. Speed is the distance an object has traveled in an amount of time. To determine speed you have to use a simple formula. There is also a thing called average speed which uses the formula before. Instantaneous speed is the speed that object goes at during a certain point in time. So, I'm bringing out Harry again, if Harry says he's gonna run two miles in 18 minutes than the answer to that would be the average speed. (Calculate that yourself because I am very sick right now so...) But when Harry slows down in the middle and speeds up again, that would be instantaneous speed!
Velocity is the last subject we have here. Velocity is an object's speed and direction of movement. It actually has the same formula as speed. The difference is When you describe speed you say "65 Miles Per Hour" with velocity, you say "65 Miles Per Hour West".
