the forces work, in this explanation I will explain how the forces and energy in the magnet cannon work. The purpose of the magnet cannon is to help show how kinetic and magnetic forces work. The magnet Cannon is an object composed of 5 balls a ruler and a magnet. One of the balls is placed on one side of the magnet (ball A), then the other 4 balls (balls B-D) go on the other side of the magnet, then the contraption is placed on a ruler. Before ball A hits the magnet there are still forces…
be used to explain how and why stuff move. These laws that Newton came up with are still used today. Newton’s first law of motion states that “an object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts on it”. An example of the first law of motion is if you are driving in your car at a very high speed and hit something, like a brick wall or a tree, the car will come to an instant stop, but you will keep moving forward. This is why cars…

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.

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…
