    Newtonian force as a covariant or contravariant quantity

    I recently came across a very cool book called Div, Grad, and Curl are Dead by Burke. This is apparently a bit of a cult classic among mathematicians, not to be confused with Div, Grad, Curl, and All That. Burke was killed in a car accident before he could put the book in final, publishable...

    Violation of simultaneity - real of frame-dependent perception?

    I am trying to understand what 'violation of simultaneity' really means, and whether it has any real importance (i.e. why was it introduced?). The Wikipedia note on this (Topic: Relativity of Simultaneity): "... the relativity of simultaneity is the concept that simultaneity–whether two...

    Is it better to accelerate into a head on collision?

    Naturally, one would think, the faster your going the more energy you will create and the harder you will hit. But take a deeper look. Under the basis that in a car accident, it isn't the "Crash" that kills you, but the stop (inertia). If you were to be involved in a head on collision with an...

    Car Accident Question

    Recently I have been involved in a car accident, and would like to figure out what was the speed of the other car that crashed into us. I only have two figures, the distance from the point of impact to where the car stopped and the mass (of both cars); and also, the final velocity which is 0...

    Suppose you are a police investigator and are investigating two car accidents. Before

    Suppose you are a police investigator and are investigating two car accidents. Before you even go to either accident scene, you know (interestingly) that both accidents were identical head – on collisions with identical cars moving at identical speeds, but in one case the cars locked bumpers...

    Velocity of Head from Car Accident

    My friend was in a head-on collision this week. They were traveling approximately 35 mph. A car collided with them head-on traveling at approximately 30 mph. The airbag deployed, and the impact caused a tremendous contusion on my friend's forehead, but no skull fractures. It's been years since...

    Car Accident Reconstruction

    My physics professor gave us a lab in which we have to do accident reconstruction. The difficulty I am having is that we have not gone over how to calculate collision with coefficients of restitution in class. So far we've only done completely elastic or inelastic, yet now he expects us to do...
