I am not a student of Physics just a retired electronics tech who is interested so I am not sure what prefix this should be under. I have some questions about the F=MA equation... 1. If there are two bricks pushed against each other so an equal amount of pressure is applied, I have Mass in each brick with no Acceleration, but Force is still being felt. How is the acceleration variable addressed? 2. If deceleration is reduction in rate of change that increases the time over distance and inversely acceleration shortens time over distance, then how is the equation effected? Should the equation actually read F=M(λV) ? These are actually precursor questions that I have for a question involving Force and Gravity measurement. Sorry if these are rudimentary and I appreciate any positive answers or comments. Thank you.
