Answer 1
decreases

INCORRECT

The force of gravity (the weight) is dependant on the mass of the object.
w=mg ...on Earth the acceleration due to gravity g= 9.8m/s2 down. return to top























Answer 2
increases

CORRECT

The force of gravity (the weight) is dependant on the mass of the object.
w=mg ...on Earth the acceleration due to gravity g= 9.8m/s2 down. Keeping this in mind, we can argue that as the mass of on object increases, its weight (the pull of gravity) will increase too. return to top



























Answer 3
Remains the same INCORRECT

The force of gravity (the weight) is dependant on the mass of the object.
w=mg ...on Earth the acceleration due to gravity g= 9.8m/s2 down. return to top


























Answer 4
return to top


























What's this question really asking?

Does the gravitational force of attraction on the Earth change as the mass changes? return to top
