It's Not Rocket Science : January 2014

Hey guys! Before I begin, I know I haven't been on in 3 weeks. Well the first 2 weeks were Winter Break, and the third was because a pipe burst in my school, so we had the week off!!
You may be wondering what the real topic for this week is. well I can say it is: Motion, Velocity, and Speed!!!!! are you putting 2 and 2 together? But first we're gonna talk about motion.

MOTION

Motion is movement. you are always in movement. Even if you are standing still, you are still moving. Why? Because you have your heartbeat, blood pumping, you have to breathe!You have to blink!! you know, unless your Edward Cullen....

There are different types of motion. Changing Position, Relative Motion, and Distance and Displacement. Changing position is exactly what it sounds like- you are changing position! If your about to jump your horse over a jump, you sit up in your saddle, put your center of gravity on your heels, and lean forward. then your horse jumps, which is also motion.

If you haven't noticed, you are always changing position. And based on your position, different things are in motion. If you are on a horse, about to turn a barrel, it may seem as if the people watching are shifting a lot. If you are one of the people watching, It looks like the horse and person are moving, which they are.

Another example would be if you were in a train. You look outside and it looks like trees are moving past you. Now lets say you are off the train, and it starts moving. Now it looks like the train is moving.

DISTANCE AND DISPLACEMENT

OK were gonna take a minute to discuss this. You know what distance is right? Distance is the actual path you have taken from point A to point B. But Displacement is the actual distance between the two points.The displacement is a number. So for example, if you are doing the clover leaf pattern (western horseback riding)You start inside the gate. then you round the barrels, and you go back to the gate. Your displacement would be 0 because the starting point is 0 ft away from the finishing point.

SPEED Now were gonna talk about speed.

What is speed? Well my friend, speed is the distance an object travels in a unit of time. Here in America, we use MPH, or miles per hour. So if I'm just chilling on my horse, walking next to a road in heavy traffic, lets say I'm going the same speed of a guy in a car going 15 MPH, how fast am I going? 15 MPH.

there is also Instantaneous and Average Speed. Instantaneous Speed is the speed you are going at that moment. And Average Speed can be found with this formula:

speed= distance
__________
time

VELOCITY

What is velocity? Velocity is the rate of change of the position of an object. And there's another formula to figure out Velocity!! Velocity= distance divided by time traveled.
