Explain this.

 >> Anonymous Fri Jan 11 20:26:44 2019 No.10289124 >>10289097What exactly are you trying to ask? Of course kinetic energy is affected by gravity, just hold an object in the air and let go. Rest mass is invariant.
 >> Anonymous Fri Jan 11 20:36:33 2019 No.10289153 quick question, since momentum changes depending on observer, energy would too right?watching a train pass youd say its momentum is large, and being on the train you would say it doesnt have any momentum

 >> Anonymous Fri Jan 11 21:07:39 2019 No.10289235 What's the difference between "energy" and "mass/speed of light"?
 >> Anonymous Sat Jan 12 11:20:48 2019 No.10290479 you know that force = mass x acceleration, right?well Einstein said that force is just another version of energy and energy is mostly photon based. and photons travel at the speed of light (c).so you replace force by energy (E) and acceleration by c^2 (acceleration is the variation of speed, and since the speed of light is constant, it's just c x c / 1).
