-- turn the light off

The equation of the graph is
Force = (mass) x (acceleration) .
The graph is a straight line that passes through the origin,
and its slope is the mass of the object being studied.
Answer:
The strength of gravity decreases.
An example of that would be if you were in space; you float around because there's no gravity.
