Terminal velocity

sort out differences in and between the dot and the car, you must think about what velocity and acceleration mean. Velocity is the rate at which the position of an object is changing. Acceleration is the rate at which the velocity is changing. Thus, when you look at the position of the dot at times shortly after you press the run button, the position will be determined almost completely by the initial velocity. If the dot has a large acceleration, then the speed will change quickly and you will

response is possible from space whereas conventional means require moving fleets or planes long distances which can take several hours to several weeks. Having large numbers of space weapons will allow attacking a target within minutes. Due to the high velocity of any kinetic weapon launched from space and the short travel time to target makes it very hard for an enemy to defend against. Some disadvantages of space weapons are that they are static in their position so a capable enemy could concentrate a

second length of time will be the time in between when the first photogate is blocked until when the second photogate is unblocked (deltaT12). The third time measured will be the time that the second photogate is blocked (deltaT2). The average velocity that it takes for the flag to pass through each photogate will be calculated by the change in the known distance of the flag divided by the time it takes to pass through the photogate in question. The acceleration of the cart can then be calculated

Have you ever wondered what it would feel like to be the lava erupting from the volcano? Well now you have the opportunity to experience this thrill of a ride! The new ride, Erosion, is opening into our local amusement park, Hershey Park. Not only will this be the coolest ride yet, but it will also be one of the only roller coasters in the park that has lots of effects and themes to make it the most realistic possible. Now you may be thinking, where is Hershey Park going to have room for another

is negative because gravitational acceleration is downward and noted by as a=-g. It is predicted and expected that the outcome for this lab is that the ball free falling would have a negative velocity and then become

Investigating the Speech Kinematics of Hypokinetic Dysarthria Secondary to Parkinson’s Disease Parkinson’s Disease (PD) is a common idiopathic neurologic disease that affects nearly 1-2% of individuals over the age of 50. It is a slowly progressive disease with a life expectancy of 15 years following the initial diagnosis (Duffy, 2013). Having relatives diagnosed with PD increases the likelihood of being diagnosed with PD. In fact, one third of individuals with two or more relatives diagnosed with

In Galileo’s Dialogues Concerning Two New Sciences, the discussion is broken up into multiple days. In the First Day, Galileo, through the dialogue between Simplicio, Sagredo, and Salviati, discusses and exemplifies various topics. They begin by considering scale in mechanics, and then later, infinity, void, and end the day by discussing pendulums and the vibrations of strings. These topics are ultimately main ideas of the text, and are explored through dialogue and proposed practicals. However,

last step is to equalize the linear velocity vector of the standard wheel to that of equation 3. ( ■(s(α+β)&-c(α+β)&-cβd@c(α+β)&s(α+β)&sβd@0&0&0) )( ■(x ̇@y ̇@θ ̇ ) )=( ■(rψ ̇@0@0) ) (4) In case of the steerable standard wheel, equation 4 can be used in the same way, if the fixed angle β is replaced by a function β(t). This equation could also be applied to the spherical wheel (because of the forces which affect the wheel and change β(t), only a linear velocity in the rolling direction exists). If
