  • Methods to Find Angles and Sides in a Triangle

    661 Words  | 2 Pages

    There are multiple methods that can be used to find the sides and angles of a triangle, such as Special Right Triangles (30, 60, 90 and 45, 45, 90), SOHCAHTOA, and the Law of Sines and Cosines. These methods are very helpful. I will explain how to use all three of them with examples at the end. The first example, Special Right Triangles, is used only with right triangles. To use this method, you need to have angle measures of 30, 60, and 90, or 45, 45, and 90. There is a "stencil" that goes with

    an object in motion is affected by the angle of an inclined ramp on which it travels. Research Question How does the angle of inclination (º) of a ramp affect the velocity (m/s) of an object in motion, if calculated using the formula [V= (2s/t) –u]? Hypothesis The prediction for this experiment is that the final velocity of an object in motion will be affected according to the angle of inclination of the ramp. The higher the inclination or greater the angle, the greater the final velocity, however

    collect is: the height and centre of mass for each block and the angle at which they fall. I will need to use five regular blocks, the board I will use to raise the blocks must be flat and level and likewise so must the surface I am working on. I will use my scientific knowledge of center of mass to predict at what point the block will fall over. I will raise the board until the block falls over and then I will record the angle at which it falls. I will vary the height of the block each time

  • The Mathematics In Sports

    522 Words  | 2 Pages

    When researching the math behind sports, I found that there are a multitude of formulas that go behind the simple actions in sports such as basketball and baseball. Basketball is a game played between two teams of five players in which goals are scored by throwing a ball through a netted hoop fixed above each end of the court. Baseball is a ball game played between two teams of nine on a field with a diamond-shaped circuit of four bases. To be successful in these sports, one must make their baskets

    and Rotation * Angles Once I had my ideas, I asked the teachers in the department what they would prefer the resource to be. Most thought that reflection and rotation was easier to teach than the others, and that more resources were available to them for that area of mathematics. The general consensus was that either of the other three was fine. So I have chosen to base my resource on angles with some properties of quadrilateral and triangles as supplement to the angles work. A factor

    clear the net and then land within the boundaries of the court. In modern volleyball the game has progressed to more of a vertical game, with jump serving. The advantages that jump serving gives have to do with the physics of projectile motion. The angle in which the server’s initial velocity has to start from is smaller, because as the height increases the slope of the parabola in the motion of the ball decreases. As the height of contact increases the path that the ball follows becomes line like

    well as figure out the best angle to send the ball where it needs to be. Throwing a deep ball is all about using the right angle with the right amount of force. I want to find out at which angle is the best to throw the ball the farthest. The angles I will test will be a low angle at 15˚, a medium angle at 45˚, and a high angle at 75˚. The force throwing the ball will be the same and the tight spiral will be assumed constant, so the only factor changing will be the angle at which the ball is being

    apparent positions of objects produced by a shift in the position of the observer” (Columbia Electronic Encyclopedia 1). Parallax is commonly used to measure distances between celestial bodies, such as planets and stars. Parallax is measured using angles that are much smaller than a degree. Arcminutes are one sixtieth of a degree and arcseconds are one sixtieth of an arminute. One example of the infinitesimal size of an arcsecond could be the width of a dime from a point of view two kilometers away

  • Hydrofoils and How They Work

    1519 Words  | 4 Pages

    What is a hydrofoil? A hydrofoil is a watercraft that is supported on ski-like pontoons while in motion, with the bulk of the hull remaining entirely above the water (Encarta Encyclopedia 2002). Hydrofoils were first seen about in 1869. Emmanuel Denis Farcot was issued a patent on a boat that he had developed to go faster through the water because of less resistance. If you look at his design, he was using many little foils along the side of his boat to lift it out of the water in order to reduce

  • Bernoulli Principle

    generated by an airplane is the angle of attack. The angle of attack is the degree measure from the horizontal that a wing is elevated or declined. When the angle of attack is between 1 and 20 degrees, the most lift is generated. To find the lift generated by a particular area of wing in a standard airfoil shape, a teardrop with the fat end facing forward, the equation L=Cl 1/2 (pV2)S. Cl is the lift coeficent, which is determined by the shape of the airfoil and the angle of attack. P stands for the

    the prism will not be refracted since the angle of refraction = sin-1(sin(0)/n) = 0, or reflected, so the images will be exactly the same. More generally, if the rays enter and leave a prism at right angles (Assuming the rays only travels through one medium while passing through the prism), the only effect on the image will be the reflection of the rays off of its surfaces. Since the law of reflection I= -I’ (Angle of incidence equals the negative of the angle of reflection) is not effected by the medium
