A group of students conducted several trials of an experiment to study Newton’s second law of motion. They concluded that tripling the mass required tripling the net force applied. What quantity were the students holding constant?

number of trials

net force

acceleration

mass*****

1 answer

no, they tried changing the mass, right?
F = ma
so, a = F/m
3F/3m = F/m = a
so, they wanted to keep a constant.
