to understand drag, as it affects the distance an object is able to travel if it is not influenced by outside forces, such as a cannons projectile. The equation for drag is shown below. F=pCA/2 v^2 p = The density of the air. C = The drag coefficient of the projectile. A = The area of the object that the air presses on. v = The velocity of the projectile. The drag equation returns a force as newtons of energy. For example, p = 1.225 kg/m3 (the density of air) C = 0.5 (the drag of a sphere) A =…

ground, it keeps moving because of inertia and accelerates 9.8m/s/s due to gravity pulling it towards the ground and the opposite happens when the slope of the hill is positive. If the track are tilted upwards the gravity still applies a downward force hence the cars…

you ever heard the term “Straight as an arrow”? Well, this isn’t exactly accurate. Arrows don’t exactly fly straight, they twist and bend as they fly. When you draw back and release your bowstring the large force of kinetic energy stored in the limbs gets transferred into the arrow and this force causes the spine of the arrow to start bending as it gets pushed forward. The archer’s paradox is this bending of the arrow around the bow as it is being loosed before it straightens out. At the moment…

In the book, The Curious Incident of the Dog in the Night-Time, many characters are put into situations where they are forced into very stressful situations. The stress in their lives causes them to act differently and treat the people in their lives differently. Two examples of characters who are forced to deal with many stressful situations are Christopher's mother and father, but each of them handles stress very differently. Christopher's mother, when confronted by stress, left the her family…

Seatwork: A. Convert the following rotation to degrees and revolution. 1. 1/3 rotation : counterclockwise 2. 4/5 rotation : clockwise 3. 13/3 rotation clockwise B. Change each radian measure to degree measure and sketch the angles in standard position. 1. / 3 rad 2. -3 / 4 C. Determine which of the following angles are quadrantal angles. 1. 850 = __________________ 3. 5600 = ___________________ 2. 2700 =…

Climbing techniques - the drop knee shouldn't be mysterious; here's a few things that everyone should know about it. What is the drop-knee? The drop-knee, also known as the Egyptian, is a rock climbing technique that reduces muscle strain in the arms. This technique let's you rotate into the rock and use your hips to push upward. With this technique, one knee ends up in a lower position and the body becomes twisted toward the other leg. It's designed to give you a longer reach as the body…

qualified and experienced in Home Station Training Support (HSTS) due to the highly charged environment and the background required to plan, coordinate and to execute Home-Station training at TSC Ansbach in support of the 12th CAB, Aviation Rotational forces and USAG Ansbach. This knowledge and skill comes with years of experience and understanding of how to develop the required training resource operational designs for all stationed units and other units utilizing the TSC Ansbach training…

The clean and jerk is an interesting lift to perform, because it incorporates a full body exercise into one explosive movement. When the clean and jerk is properly performed, it combines a deadlift, upright row, front squat and a push press all into one quick movement. The lift was initially implemented as one of the original lifts in Olympic weightlifting competitions, normally performed after an athlete clears the snatch lift. When setting up to perform this lift you will need to be on a…

Lesson 1: Investigating physical forces. Learning objectives: Students will be able to investigate and explain how applying or removing physical forces of varying intensity can cause objects in their environment to move, stop moving, stay at rest, or change direction. Content: Wind/ physical force:Collected from http://handmadekidsart.com/wind-power-car-races/ -The surface area contacting the wind force will affect the movement. -The high speed of the wind will allow the object to move faster.…

Have you ever wonder what the difference IS between a longboard and a skateboard? You will learn the many differences and similarities between the two. First I will tell about the Skateboard, A skateboard is 28.5 inches in length and 7.5 inches in width. It has small wheels only measuring at 2.04 inches wide. The wheels are designed for short travel and traction. Because of this that means it isn't made for cruising like a longboard. The average truck size for skateboard is 6.5 inches in…
