This little box‚ about the size of an iPhone‚ is the Leap Motion‚ a completely hands-free virtual reality mouse. It may not be as nice as the nanobots‚ but it’s definitely useful for the common nerd! When plugged into the USB port of your computer and its software installed‚ this device creates a 3D interaction space around it’s sensor bar‚ containing an area of approximately eight cubic feet. Leap Motion Inc.‚ the developer of Leap Motion‚ claims this device is able to sense and track your individual

In 1687‚ Sir Isaac Newton published what are known today as Newton’s three laws of motion. If these laws didn’t exist‚ motion and life would not exist. His three laws are accurately relative to what "normal" speeds are on earth. Newton’s first law is most commonly referred to as the law of inertia. The law states that an object that is at rest will stay at rest unless an unbalanced force acts upon it‚ and vice-versa. If an object is moving and there is no force to move the object in a different

ASP 0501 EXERCISES – circular motion 1 A car travels at a constant speed around a circular track whose radius is 2.6 km. The car goes once around the track in 360 s. What is the magnitude of the centripetal acceleration of the car? 2 An astronaut in a chamber moves on a circular path‚ much like a model airplane flying in a circle on a guideline. The chamber is located 15 m from the center of the circle. At what speed must the chamber move so that the astronaut is subjected to 7.5 times the acceleration

CASE: Research in Motion (RIM) Introduction Research In Motion (RIM) is the company behind BlackBerry‚ one of the best-selling smartphone brands in the US. RIM first went public in 1997 and introduced BlackBerry as a paging device that allowed user to read emails. Soon‚ BlackBerry evolved into a full blown smartphone: a call‚ text‚ email capable organizer. It first gained ground in the business community and government‚ with its high-se curity and essential business features. BlackBerry was

Where Does the Answer Lie with Gun Control? Death‚ violence‚ individual rights‚ crime‚ and cause are many words that arise when researching the controversial topic of gun control. This issue revolves around the Second Amendment of the United States Constitution that states: “A well regulated Militia‚ being necessary to the security of a free State‚ the right of the people to keep and bear arms‚ shall not be infringed.” (U.S. Constitution. Amend. II‚ Sec. 1.). Is there a black and white answer

EXERCISE 7 - Rotational Kinematics and circular motion 1. A wheel has a radius of 4.1 m. How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30°‚ 30 rad‚ and 30 rev‚ respectively? 2.1m‚ 1.2x102 m‚ 7.7. x102m 2.

constant. If a ball is attached to the end of string and swung at a constant speed (i.e. only the direction of the velocity is changing not the magnitude) then there must still be an acceleration. The acceleration is directed towards the center of the motion. This acceleration is call centripetal acceleration! 2.6.2 State the expression for centripetal acceleration. The acceleration of any object moving in a circle at a constant speed is given by the equation: (1) a⃗ =v2r It is important to note

Handgun vs. No Gun Do you think it is appropriate whether people should own a handgun or not? The article “The Accessibility of Guns Protects Lives” by David M. Huntwork and “The Accessibility of Guns Lead to Gun Crime” by Alan M. Ruben both have significant perspectives regarding if it is secure or hazardous to own a firearm. There can be a debate of whether guns can protect our lives or can lead to gun crimes. There are several opinions stating that firearms are beneficial to own in one’s lives

law of motion: For every action‚ there is an equal and opposite reaction. How this applies to our bottle rockets that we constructed‚ is that when we release‚ the water and air pressure comes out of the bottom. That pushes against the ground‚ the equal and opposite reaction is the earth pushing back up. Whatever object has less mass moves. In this case‚ the rocket has less mass than what it is pushing against; the earth. When we created our rockets‚ we had to keep all 3 laws of motion in mind
