a) quantity that causes displacement
b) quantity that keeps the object moving
c) the mass of the object
d) the quantity that changes the velocity of an object
c) is not the right choice. I believe that answer is a) is this correct?
Net force could be zero, and displacement increasing (as in something in constant velocity).
Relook at d. Netforce=mass*acceleration
The answer is (d). The quantity that change the velocity of an object.
The answer is E. I had it on a test
