    Should I Switch to Physics for a Career in Nanotechnology?

    Yes it is Imperial College London. The philosophical aspects of physics are just a side interest of mine. One of my biggest interests is the mathematical aspects of the field, besides the fact that physics gives you an understanding of the whole universe, which is the most fascinating thing...

    Should I Switch to Physics for a Career in Nanotechnology?

    Yes micromass that is the problem I have. The thing is that the best nanotechnology programs are only available in masters degree, so in order to enter the field I would have to major in something. My current options are either Materials Science and Engineering or Physics. I'm just worried...

    Should I Switch to Physics for a Career in Nanotechnology?

    Oh I'm sorry for the misunderstanding. When I say MSE I mean Materials Science and Engineering. As I mentioned I am a high school senior.

    Should I Switch to Physics for a Career in Nanotechnology?

    I will certainly look into the possibility of reading physics as a minor. I don't know what the lower degree is. May I ask why was it a "mistake" to flunk out of engineering due to love for physics? I just don't want to spend 4 years doing something and thinking I could be enjoying myself a...

    Should I Switch to Physics for a Career in Nanotechnology?

    Thank you for your welcoming! I got an offer from Imperial College London to study MSE. And up until last month I was absolutely sure that I wanted to study that. But i suddenly feel drawn to a physics major. Understanding the universe seems like one of the biggest challenges, and so far I...

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    Calculating the acceleration of the block do you take in consideration the weight of the wheel even if translationally at rest?

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    How so? Well then show me your work please

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    Yes, but when the block comes to rest, all of its translational kinetic energy is transformed into rotational kinetic energy on the wheel. That is what my previous calculations demonstrated

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    But the wheel as a whole does not move through space. It only spins around it's center of mass. Kinetic energy is only rotational.

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    It says that the wheel is supported. There is no translational movement. Only rotational

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    But the wheel is attached isn't it? Therefore there would only be rotational kinetic energy..

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    Ok let me try again. The energy of the system must stay the same, therefore, the variation of energy of the block must be the same (symmetric) as the variation of the energy of the wheel. The loss of potential energy of the block will result on the increase of the kinetic energy. KE=PE...

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    K=(1/2)Iw^2 I = moment of inertia= (1/2)mr^2 w = angular speed = v/r K=1/2*1/2*m*r^2*(v/r)^2 K=1/4*m*v^2 When an object has translational as well as rotational motion, its total kinetic energy is the sum of the translational kinetic energy and the rotational kinetic energy.Please check my...

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    Yes! Now it is correct! Keep in mind that both velocities are squared in that particular equation
