#1 Design an experiment to determine how changing the velocity or mass of an object impacts its kinetic energy. Explain the measurements you’ll make and discuss the number of experimental groups you’ll include and trials you’ll perform. Also identify the independent, dependent and controlled variables.

#2 Below is a cart at different positions along a rollercoaster. Compare the potential energy of the cart at position A, B, C and D. Also, compare the total energy of the cart at position A to position C.

#3Compare the potential energy of an object in space to an object resting on Earth’s surface. Specifically, how would the potential energy of a person on a plane compare to an astronaut traveling on a spacecraft to Mars?

You have been consulted by the mobile phone company hookup about a new augmented reality product called “brows”. they want to develop an alternative to google glasses, which, you recall, is a proposed new product which plans to superimpose a whole range of wireless google services over the user’s ordinary vision of the world. these appear in little circles and ovals, and let you phone people, take photographs, navigate across cities and inside buildings, find shops and update your social media. brows would do this too, but not be limited to special google services. the user would wear a small cylinder-shaped device designed to fit on top of their existing eyewear (glasses or sunglasses). it would project a reversed image onto the inside of the lenses, the reflection of which would be in focus for the user. instead of voice control, the user would control the device by eye and neck movements, which the device would track. the device would connect via bluetooth to the user’s phone, which would supply most of the computing power and wireless connectivity. hookup also wants to know what existing services would be most in demand, and which would not work well with brows. using your knowledge of augmented reality, wearable technology and interface design, is the project feasible? if not, why not? if feasible, how could the product need to be modified for a better experience?
