If the force of gravity increases, which measurement will change and how?

weight increases

weight decreases

mass decreases

mass increases

In physics we refer to how heavy the object is as the mass.

Fg = mass x acceleration due to gravity

Force is directly proportional to mass, thus if force of gravity increases mass also increases.

If the force of gravity increases, then weight increases.

Simple easy explanation: The force of gravity IS what we call "weight".

Better explanation: The force of gravity between two masses tries to pull the masses together. If gravity increases, then the force pulling the masses together increases.
