Vectors And Projectiles
After successfully completing the first two videos of the Paul Hewitt series, I have been drawn to this course. The third video of the series reviews the concepts of vectors and projectiles. In this video Paul goes over a lot of previously stated formulas. The ideas of how fast or hoe far an object travels are restated.
The idea of how fast an object travels is known as its velocity. The velocity is found by finding how far an object travels over a period of time. It may be easier to multiply the pull of gravity, which in a free falling object is ten meters per second accelerating, by the seconds the object remains it the air. The product will result in how fast the object was traveling.
The idea of how far an object travels is known as the distance. The distance can be found by multiplying the amount of time an object is in the air by itself and then multiplying the results by five. For example, a rock dropped off a cliff takes five seconds to strike bottom. Multiply five times itself and then by five. The rock was dropped from 125 meters high.
My favorite part of this video was when Paul explained about a time he went on a church trip hang gliding. The purpose of the story was to get a point across about dropping a rock off a cliff and being able to determine the distance to the bottom. The humor in this helped me grasp the concept of time. The humor was he dropped the rock and it rolled down because there was not a straight drop. The point he was trying to get was to throw the rock. Not to throw it up or down, but to throw it straight and it would strike the bottom at the same time as it would on a free fall.
Select and identify TWO concepts presented in the video you find significant as an early educator and explain why you selected these concepts (7 descriptive/detailed sentences)
I really enjoyed this video. It's crazy the amount of informaton that gets packed into a three minute video. I think the cartoon and music that accompanies it helps because you're being entertained as well as informed. I think it's easier for me to remember a fun fact from the video versus reading a whole chapter from a book.
4. How would you explain your results using the terms: impulse, momentum, force, and time? Use equations to help you explain the results.

Hurling an object towards one’s enemy may seem as old as time itself. People have hurled fists at each other, thrown spears, and launched giant rocks into enemy territory. The use of catapults, and other objects that hurl projectiles, also seem as old as human civilization itself. The effectiveness of the catapult in flinging objects over a great distance and causing destruction is due to a few basic physics principals that govern force, energy, motion, speed and mass to name a few. The design of the catapult denotes a change in modern warfare to the engineer behind weapons being just as important as the actual soldiers and people who use them.

The velocity was then compared. Momentum:.. Momentum is defined as the product of mass and velocity in a body. It is a vector quantity and is measured in kg.m.s-1 (M.Mann, 2013). The Law of Conservation of Momentum states that the total linear momentum of an isolated system remains constant.
The definition of a projectile is an object that the only force acting on it is gravity. Projectile motion is the path the projectile takes. We saw and used this topic a few times in our project. The first time we saw it was when the marble was flew out of the pipe and was in the air. The second time we used the topic to make sure the trains fell on the lever in the correct spot so the golf ball would roll. The third time it was used, was when the board fall on the balloon. It fell as half of a parabola since it started standing up.
F = ma : where F is force; m is the mass of the body; and a is the acceleration due to that particular force
If a force acts on a body, the body accelerates in the direction of the force. In the example of the force of gravity, small things like textbooks are pulled downward toward the center of the large mass of the Earth, not up into space, even if some people think that this might happen. Isaac Newton was the first to conceive of weight as the gravitational attraction. between the body and the Earth. The force that results from the gravitational attraction of the Earth on its surface is what we call weight. Science has chosen to measure the mass of objects in units that are roughly equivalent to the weight of those objects on Earth.
In our text we began our study of physics with motion because motion is a dominant characteristic of the Universe (Kirkpatrick, 21). In class we learned that speed is the distance traveled divided by the time taken, s=d/t. The definition of velocity is very close to that of speed except that direction of an object is also taken into account.
Physics can be used to explain a lot of things. In this paper I described some basic concepts in physics that are relevant to basketball, particularly the three main parts of basketball, shooting, dribbling and passing. So the next time you are out shooting some hoops just think of all the physics that are being applied and you could be one step away from being a physicist, and have fun.
I ended up really liking the poems that we listened to and when I got home that night I decided to listen to them again. I did this, because there are always things you miss the first time. So, the second time I listened to the videos the metaphors the poets used really influenced me. The poem that Sarah Kay wrote, “If I Should Have a Daughter”, let me know to never give up no matter how hard life gets. It taught me to set my goals high and never take no for an answer.
According to Newton’s Second Law of Motion, the vector sum of the total forces in a system is equal to the product of the mass (m) and acceleration ( a ) of the system.
There are five critical parts to understanding projectile motion and what it is: acceleration, velocity, displacement, maximum and minimum height, and the vertical and horizontal components.
