This was an exam question. The question simply states "What does a force acting on an object do to that object's motion?"
The answer is A force changes an object's momentum. I thought the answer was A force changes an object's momentum and changes an object's acceleration.
My thought process is that if a force acts on an object then the object must change acceleration.
Momentum = m*v;
F = ma; F = m ((v2 - v1)/t)
I feel in order to have a change in momentum there must also be a change in acceleration at some point.
Why am I not correct in this assumption? Many thanks!
