Rockets‚ space shuttles‚ and space stations are all used for many different reasons and there are many different examples of all three space crafts. A rocket is a one time use craft that is powered by gases being forced out of a small hole very fast causing the rocket to fly.Space shuttles are multiple use crafts that are propelled into space by rockets that are attached to the shuttle and then the shuttle moves around in space under its own power. Space stations are crafts that stay

marble are shown below. Notice that the size of the vector remains the same but the direction is constantly changing. Because the direction is changing‚ there is a ∆v and ∆v = vf - vi ‚ and since velocity is changing‚ circular motion must also be accelerated motion. vi ∆v vf -vi vf2 If the ∆t in-between initial velocity and final velocity is small‚ the direction of ∆v is nearly radial (i.e. directed along the radius). As ∆t approaches 0‚ ∆v becomes exactly radial‚ or centripetal.

Ariane 5 Rocket Disaster On the 4th of June 1996‚ around 40 seconds after initiation of the flight sequence‚ the maiden flight of the Ariane 5 Launcher ended in failure. An independent Inquiry Board was nominated to determine the cause of the launcher failure‚ and found that the inertial reference system (IRS) was the cause of this incident; a system error propagating through the control‚ commanding large corrections in altitude leading to the destruction of the vehicle. During the development of

1) A small rocket is being designed to make wind shear measurements in the vicinity of thunderstorms. Before testing begins‚ the designers are developing a simulation of the rocket’s trajectory. They have derived the following equation that they believe will predict the performance of the test rocket‚ where t is time elapsed in seconds. The equation gives the height above the ground level at time t. The first term (60) is the height above ground level of the nose of the rocket. height = 60 + 2

Big screen or small screen? Motion pictures captured the hearts of audiences from their birth and have won millions of devoted fans around the world. Even though later technological developments‚ such as the television‚ the video and more recently the DVD‚ made private viewing of motion pictures possible‚ the big screen has not lost its appeal. Based on my experiences‚ I prefer going to the cinema. There are several reasons for the movie theaters’ permanent popularity. First‚ even the most sophisticated

Free Newton's laws of motion Classical mechanics
Newton ’s laws of motion Newton ’s laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries and can be summarized as follows: 1. First law: The velocity of a body (a state of rest or of uniform motion in a straight line) remains constant unless the body is compelled to change that state

Answer: Scalar: Volume‚ mass‚ speed‚ density‚ number of moles‚ angular frequency Vector: Acceleration‚ velocity‚ displacement‚ angular velocity A scalar quantity is specified by its magnitude only. It does not have any

Research in Motion Porter’s Five Force Porter’s Five Force Model There are some different approaches available when measuring the profitability in a market‚ or industry. I choose to use the model by Michael E. Porter‚ where the profitability potential of an industry‚ described as the long run return on investment‚ is reliant on the degree of competition in the selected industry. The five forces that Porter mentions are; threat of entry‚ supplier power‚ buyer power‚ threat of substitutes and industry
