No doubt force can be measured but it also can be felt....
Acceleration cannot be felt, it can only be measured.
Force concept is
definitely more subjective and intuitively understood than
acceleration. I do not think there can be any two opinions about
this because this is a matter of experience of all of us.
Acceleration by all accounts is a derived quantity L/T*2.
As a matter of fact I have once posted a letter to this list
saying that motion (not acceleration) is more fundamental than
time. Because without motion there is no time. When
nothing happens, there are no events and there is no time.
