What is kinematics in physics? If vector 1 has a magnitude of 3, and a direction of 30 degrees below the negative x-axis, and vector 2 has a magnitude of 4, and a direction of 80 degrees below the negative x-axis. What will be the ...
In the world of physics, acceleration, velocity, and forces are all represented by vectors. A vector is a quantity that has both a direction and a magnitude. A magnitude is an abundance or a mathematical amount of something. Displacement is also a vector quantity, which is the difference in...
I might as well add this in here. Really, I don't plan on talking about Khan Academy for a while. Too many other cool things to talk about. I think there are really two parts to learning physics. There is the part that deals with building models and there is the part that deals ...

Conservation is assumed to be born in the phase, just as momentum is for instance. In other words, all known phenomena in physics are deterministic, classical and real, in the sense that information does propagate locally and experiments conducted statistically do hide latent variables....
Does anyone know how to represent the normal unit vector in COMSOL 4.2? e.g., n=(nx, ny, nz). I need to impose a normal displacement field in the electrostatics module. However, in COMSOL 4.2, I only find the option to impose the x, y, and z components of the displacment f...
What are the torques on the particle about the origin, in unit-vector notation?Torque:Torque is a physical quantity that tells about a rotational effect on an object. The torque acting on an object about the origin is equal to the...
