A FORCE is a push or a pull
Gravity as we experience it--is a force that pulls toward the center of Earth
Inertia is an objects resistane to change in motion.
Buoyancy is a force that pushes up
friction is the action of one surface or object rubbing against another

# data[].attributes.body
the strength of gravity depends on the mass of the object and the distance between them

when 2 objects are close together the force is greater when objects are farther away the have less force

# data[].attributes.body
unbalanced forces
forces acting on an object result in a net force causing it to move
balanced forces
no net force so the objects motion does not change
force definition a push or pull in a particular direction
forces affect how objects move they cause motion they also cause objects to slow down stop or change direction
forces also cause acceleration
example your playing tug of war with your friend the stronger force is going to win and that would be unbalanced if you and your friend have an equal force then the rope wont move and it will be an equal force
