When 2 forces are not equal and they work against each other.
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
Inertia, friction, gravity
Gravity and Inertia
Inertia and force
friction and gravity
In terms of general physics; momentum, gravity, kenetic energy, inertia, and friction
Gravity and friction can affect inertia. Another force that can affect inertia is the mass of the object that is being moved.
centrifugal (forces that bring together) and centrifugal (forces that divide)
Perhaps you mean friction or inertia.
Inertia is one of the forces of nature that impact the forces of the moon and its orbit through the solar system.
inertia and gravitational pull

Gravity and Inertia. :)
Inertia is the property of matter by which it remains in constant, uniform motion unless acted upon by an external force. Gravity is an ever-present external force.
because a heavier person has more inertia, and therefore the forces that work to slow the person down, i.e. friction, wind resistance, whatever, will have less effect on an object with more inertia than less inertia
