I see, that makes sense. So the f=ma in this instance simply won't help me to calculate the force being applied by my finger to the car - is that correct?
If that is the case then is there a simply way to calculate said force?
Thank you all for the replies.
I can see the galaxy idea because in effect there is no resistance to my movement which will slow me down and so inertia (momentum) keeps me going along at a constant velocity i.e. no extra force is required to keep me moving.
So then, I'm either close to...
Alright so f=ma
I know the difference between mass and weight so that's alright. Now I'm heavy (96Kg); If I'm moving forwards at a rate of one metre per second (with the passing of every second I move forward exactly one metre) then is 'a' equal to one?
This confuses me in that I'm not...
