Definition of Work |
Hi! Please, does someone know who defined originally work as int F dx?
I think it was not Newton, or am I wrong?.

Nice post.
Energy is the ability to do work, therefore it has the same units.
Since velocity is the integral of acceleration v = 1/2 at^2
and momentum is defined as mass * velocity p = mv
and force is mass * acceleration F = ma
force is the derivative (or rate of change) of momentum.
Momentum being a conserved quantity (the gun kicks back
by Newton's third law) Mv +mV = 0
W = 1/2Mv^2+1/2mV^2
Where M = m, v = V and W = mv^2
That was yet another thing the crank Einstein mishandled.
