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 ...

This is analogous to how, in undergraduate mathematics and physics, vectors in Euclidean space are often depicted as arrows of a given magnitude and direction, with the initial and final points of this arrow being of secondary importance only. (Indeed, this depiction of vectors in a vector spac...
In quantum physics, a strong form of G-symmetry is to couple to a G-connection, suggesting that we should formulate 4d {\mathcal {N}}= 8 supergravity on Riemannian spin 4-manifolds M together with an {\widetilde{E}}_{7(7)}-bundle P\rightarrow M and a connection on P. The spin ...
What is a net force? What is a constant force in physics? What does net force mean? How to calculate the force constant A) A constant net force is applied to various masses. Sketch a graph of the magnitude of the resulting acceleration as a function of mass. B) A variable net force...
