In which situations is gravitational potential energy present? check all that apply. a person walks up a flight of stairs. a person runs across a room. wind blows against a steel table anchored to the ground. wind lifts a balloon into the air. a weightlifter holds a barbell on the ground. a weightlifter holds a barbell straight overhead.

Option (1), (4), (6)

Explanation:

The energy possessed by the position or configuration of a body is called it's potential energy.

Gravitational potential energy is defined as the energy possessed by the height of object from the ground level.

Here, a person walks up on the flight of stairs has cover some height from the ground level, so it has gravitational energy.

Wind lifts a balloon in air also have gravitational potential energy.

Weightlifter lifts a barbell overhead also cover some height to lift the barbell, so it also have some gravitational potential energy.

do you have a formula possibly
