2
A doubling of the mass results in a __________ of the acceleration (if force is held constant).
2

Explain what is meant by 'terminal velocity.'

4
The more momentum that an object has, the harder that it is to stop. Thus, it would require a __________ amount of force or a longer amount of __________ or both to bring such an object to a halt.
