... tangential velocity of a point anywhere on the rotating body or in the shaft of the motor by using the tangential velocity equation v = r*w , as shown in Figure.4. r is the distance from the axis of rotation. Figure. 4:Calculation of Angular velocity The output power of a motor could be calculated by using this formula, P = Torque.w where w the angular velocity[7]. Knowing and computing all those parameters of the motor which are torque, angular velocity and output power
A Study of the Changes in River Processes This is a study of the changes in river processes along the long profile of a river. To study this we will use a sample river. The river the study will be based on Loughton Brook, which is a river situated in Epping Forest in Essex and is also a tributary of the river Thames. A journey will be made to the river and measurements will be made at three different sites. The measurements that were taken will be studied so conclusions
Angular projectile motion is used to calculate how far an object with an initial velocity that is projected at an angle to the horizontal will travel horizontally. It can also be used to calculate the maximum height reached by the object and how long it was in the air for. When solving angular projectile motion problems, one must consider the following steps. To begin with one must calculate the horizontal acceleration of the object, keeping in mind that the vertical acceleration is 9.8 m/s2 due
definition of velocity is very close to that of speed except that direction of an object is also taken into account. Soccer is a sport that is all about motion and how to use movements most effectively. Speed and velocity are very important when it comes to motion because with out them there would be no motion. When playing soccer speed is essential to being a productive player. The game is fast paced and so the players must also be quick on their feet. Soccer players may not know that velocity is essential

Decreasing the torsion in the ropes of the wooden arm would make the projectile travel at a slower velocity. To calculate the t... ... middle of paper ... ...ed. Another disadvantage is that the mangonel was not that accurate. The range was determined by the mass of the object and the strength of the catapult itself. Catapults were the weapon of the
Acceleration equals final velocity minus initial velocity over the final time minus initial time. The cause for the acceleration down the mountain varies by the mass of the person, wind, snow condition, and the type of snowboard that you are riding. Also, hopping once or twice should increase the acceleration time. Acceleration is not only the change of speed, but also occurs when slowing down to come to a stop. This type of acceleration is called negative acceleration. Velocity- velocity can be measured
bowling many things are going on that apply to bowling. There is displacement, velocity, gravity, and acceleration. There is also an opposition to motion, which is friction. The displacement would be the bowling ball going from the position of leaving the hand to where it rests at the back by the pin collector. The velocity of the ball would include the speed and direction of the ball. The equation to find the velocity of the ball would be the displacement divided by the time taken to reach the destination
players, such that less players cover more ground need to be well illustrated. This paper connects the concept of mathematics to volleyball, explaining various models of a served volleyball in details. To explain these models, the forces as well as velocities acting on the ball are described mathematically. The three most important forces considered here include the force due to gravity, force from the spin, and the force due to air resistance. Dimensions, Parameters, and Notations Illustrating the arrangement

include calculating the velocity of the golf ball after the club and ball collide, the mass of the club head, launch angle, the shape of the club face, and finding the optimal golf ball. Intuition tells us that the larger the velocity of the club head at impact with the golf ball, the larger the velocity of the golf ball after the impact. To calculate the velocity of the golf ball we need to consider the relationship between the velocity of the club head to the velocity of the golf ball. If
Angular momentum and its properties were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body, following a curved path, has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum.Torque is the angular "version" of force. The units for torque are in
Introduction The purpose of this experiment was to understand how different variables can affect the period of oscillation of a pendulum. Aim: To determine the acceleration due to gravity, by varying the length of an inelastic string and measuring its corresponding period of time for each experiment. Apparatus used Retort stand Clamp Stop watch Pendulum bob Ruler Counter weight Rigid support Inelastic string Vernier caliper Theory According to Crundell (2001, p231) Simple
escapes the planet's gravity is called the "escape velocity." As you would expect, the escape velocity depends on the mass of the planet: if the planet is extremely massive, then its gravity is very strong, and the escape velocity is high. A lighter planet would have a smaller escape velocity. The escape velocity also depends on how far you are from the planet's center: the closer you are, the higher the escape velocity . The Earth's escape velocity is 11.2 kilometers per second (about 25,000 M.P.H
Intro: In basketball, there are many instances where angular motion is apparent. Angular motion refers to all points on an object moving in a circular path about a fixed axis. The limbs of our bodies exhibit angular motion around our joints, so most of the movements involved in playing basketball display some form of angular motion. The two important biomechanical aspects of angular motion are Angular Kinematics and Angular Kinetics. These subdivisions of biomechanics are significant because understanding
only influences the vertical component of motion, not the horizontal. Similar to the height vs. time graph, the dancer’s trajectory in a jump is also a parabola. If the dancer jumps so that the center of gravity rises by two feet, and the horizontal velocity is 10 ft/sec, the path will look like this. To find the average speed of an object, the total distance the object or the dancer traveled over the time it took to get there. For instance, if a dancer moves five meters toward the left of the stage
Anatomical Analysis Tae Kwon Do is a Korean, unarmed martial art and is best known for its kicks (Park, 2001). The roundhouse kick is a turning kick and happens to be the most commonly used kick during competition (Lee, 1996). For this reason, the roundhouse kick will be analyzed in reference to sparring competition. The roundhouse kick, a multiplanar skill, starts with the kicking leg traveling in an arc towards the front with the knee in a chambered position (Pearson, 1997). The knee is extended
Angular momentum is the relationship between Rotational Inertia and Rotational Speed. More simply, it is the tendency an object has to continue moving in a circle or spinning. Angular Momentum = Angular Velocity x Rotational Inertia When a figure skater pulls their arms closer to their body, they are reducing their Rotational Inertia, making themselves more aerodynamic. In order to sustain this and maintain their momentum, the Rotational Speed must increase. Angular Conservation Angular momentum
The Physics of the High Jump The world consists of many phenomena. Some of them are mysteries to us as human beings, while many others can be explained. Progressively over the centuries, science has helped us to better understand the spectacular things that physically affect the human race and the earth. Almost every single thing that deals with the physical aspect of our existence can now be explained through physics, which in turn helps us to better understand our surrounding environment. Where
Fishing contains a wide variety of physics. when you cast you are using projectile motion and rotational motion. when you hook a fish it will often use the drag from the current agenst you. Immagine draging a fish through a swift current. You deal with the tention of your line, and the friction of the line through the guides. you also deal with friction when you use a drag. Reels One of the key components of your fishing gear is the reel. http://www.eangler.com/eangler/proshop/reels.asp
