Professor Chocos Freshmen English 102 February 6‚ 2013 Do What You Love “ There are three apples important in this world‚ Adam’s apple‚ Newton’s apple and Steve’s apple”. This was one of the lines quoted by Steve Jobs in one of his speeches‚ which signified the level of confidence and faith he had in his work. The only way to be satisfied is to do great work‚ which can be attained only by loving your own work. This was the main idea of his commencement speech in

velocity. It is made up of the sum of the angular momentum of the body’s segments. The variables that influence angular momentum are the rotational speed of the gymnast‚ point/center of rotation‚ and the configuration of the gymnast’s body. For a gymnast of a given mass‚ how that mass is configured about the point of rotation determines the moment of inertia at an instant of time. An example is how the moment of inertia progressively increases as the gymnast goes from a tucked to a piked to a layout position

and pulls his legs up towards the sky‚ leaving his body in a perfect upside-down position to enter the water head-first. In order to perform a front dive with a somersault‚ it requires a full flip of the body and therefore it takes a quicker rotation to cover such an angular distance. The diver takes off from the diving

Swing Start the club head back from the ball 3 feet. Your body should stay in an aligned position‚ wrists and arms firm‚ and a slight bend of your knees. Move the club to waist high‚ keeping your lead arm straight‚ your hips with a slight rotation away from the ball. Step 3- The Backswing Bring your club three quarters of the backswing. The shaft of the club should be vertical‚ the club head above your head. Step 4- Finish of the Backswing Take the club head the entire way back

An Analysis of the Volleyball Jump Serve | Dr Marion Alexander‚ Adrian Honish MSc - Sport Biomechanics Lab‚ University of Manitoba‚ Canada | IntroductionOne of the most dramatic skills in modern volleyball is the spike serve‚ or the jump serve‚ which provides an exciting and dynamic skill that is captivating for players and spectators alike. The player starts about five meters behind the end line of the court‚ uses a fast and explosive run up‚ a dynamic spike takeoff and an exciting spike

Any slight change or rotation can cause the object to change direction in general making it not move toward the specified direction. Eg: ball thrown by a man in a straight line. Circular motion Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform‚ with constant angular rate of rotation (and constant speed)‚ or non-uniform with a changing rate of rotation. The rotation around a fixed axis of

object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis of rotation. A common example is to think of

Working principles of vibrating screen: The motor drives the eccentric block of the exciter to do high-speed rotation through the coupling. The rotating eccentric block produces strong centrifugal force to stimulate sieve box to perform certain amplitude circular motion. Being affected by the impulse from the sieve box‚ the materials on the oblique screen surface

Planes which contain the rotation axis intersect the surface in the meridians and the angle between any one meridian plane and that through Greenwich (the Prime Meridian) defines the longitude: meridians are lines of constant longitude. The plane through the centre of the Earth and orthogonal to the rotation axis intersects the surface
