Force of gravity and support (normal).

Explanation:

Gravity is the force pulling us downwards to earth.

Whereas,

Force of support, also called normal force, is the force that is holding us on earth.

therefore

these two forces are equal, unless you are flying or moving down,

Some other examples can be light hanging from the ceiling which has the two forces:

tension and gravity force.

tension is the force grabbing the light bulb from falling, and the gravity is pulling it downwards, and since the bulb is neither going downward nor upwards, the two forces grabbing both upwards and downwards are equal.
