Question

When the mass of an object increases, the force of gravity

increases.

decreases.

remains the same.

becomes irregular.

Answer 1

i think its b what do you think.

Answer 2

gravity is acceleration, gravity is not a force
so no matter how much you change the mass of an object, it will still accelerate at the same rate.

Answer 3

hmm.. conflict with @roadjester, i understand what you mean but in physics we need to be careful
"gravity is acceleration, gravity is \(not\) a force"
actually, from what i learned, gravity is a kind of force.. it is the attraction force between objects..

"\(no\ matter\ how\ much\ you\ change\ the\ mass\ of\ an\ object,\)
\( it\ will\ still\ accelerate\ at\ the\ same\ rate.\)"
according newton's 3rd law, acceleration is inversely proportional to mass, so it means that the greater the mass the lesser the acceleration. Therefore the mass of the object matters

The force of gravity is equal to mass x acceleration due to gravity (which is approximately 9.81m/s^2). Fg is directly proportional to the mass,
THUS,
"When the mass of an object increases, the force of gravity \(\underline{INCREASES}\)"

Answer 4

Yes, force F = m g
and though g remains unchanged, F increases if m increases.

Answer 5

@Data_LG2
"it is the attraction force between objects"
I agree that there is indeed gravitational force which is defined as
\[F={ Gm_1m_2\over r^2}\]

the question asked what would happen to the force of gravity, which in itself is somewhat vague. If the question asked what would happen to force, I would be inclined to agree with your correction.

In regards to newton's third law, you are incorrect. That is actually newton's second law of F=ma or a=F/m

At the moment, I will not make any claims as to whether or not I am correct. I think it would be best if @twest clarifies.

Answer 6

oh yeah second law, my apologies @roadjester

Answer 7

"Force due to gravity" would have been clearer and is my guess at the meaning.
