(a) In Newtonian mechanics force and acceleration are
related by the familiar equation f = ma. Explain briefly how the
definition of force is modified in special-relativistic
mechanics.
(b) In special-relativistic mechanics, under what circumstances is
force parallel to the acceleration it produces?
I will be glad to see your comment if you have any query and thumb up if you are satisfied. Thanks...

We spent an entire semester talking about Newtonian mechanics (F-ma, KE-1/2 mv) so that knowledge must be important. The truth is that those equations are almost precisely correct except for the fastest particles. Let's see if we can find out how fast something must be going for those approximations to be off by a signficant amount. Assume we have a object with a mass of mo 1gram. 1) What if the object is going 0.03 c. What is the object's...
Multivariable Calculus help with the magnitude of angular
momentum: My questions is exercise 4 but I have attached exercise 1
and other notes that I was provided
4 Exercise 4. In any mechanics problem where the mass m is constant, the position vector F sweeps out equal areas in equal times the magnitude of the angular momentum ILI is conserved (Note: be sure to prove "if and only if") (Note: don't try to use Exercise 2 in the proof of...
In F=ma when summing the forces, I know they must all be in the same direction (along with the acceleration), but should they all be acting on a single point also (or acting relative to a point)? So if you had two forces acting on an object and say one is acting on the center and one is acting on some distance from the end, you must set up an origin point, and have two position vectors from the origin...
Sample Class Problems-Force and Acceleration Prob#l: Two people are pushing a stalled car (the mass of the car is 1850kg). One person applies a force to the car, while the other applies a force of 395N. Both forces act in the same of 560N also acts on the car, but in a direction opposite force arises because of friction and the extent to which the pavement opposes Find the acceleration of the car. direction. A third force to that in...

3. For experiment A, use equations 1&3 to develop a general equation for the value of tension (T) based on the values of the two masses. You will need this later to answer lab question (4), so write it in now. 4.

1. Using F(r) = -y/r2, show that the equation of motion in a central force, namely a na = -u(0) - EF (), produces the solution u(b) = (-1(1 + e coso) What are the expressions for C and e in terms of the parameters of the problem? 2.

Question 7 is related to the force vs mass graph that is
provided and the first section of the excel sheet. Question 3 has
to do with the force bs acceleration graph and second section of
the excel sheet. The first two files are showing the equations that
are supposed to be used to find these answers. Any help would be
greatly appreciated.
