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

A person walks up a flight of stairs.

Wind lifts a balloon into the air.

A weightlifter holds a barbell straight overhead

Explanation:

Gravitational potential energy is possessed by a body due to virtue of its position (height).

A body placed some height above the ground possesses gravitational potential energy which is equal to the work done to lift it.

Thus, a person who walks up a flight of stairs, a weightlifter holding barbell straight overhead and wind lifting balloon into the air have gravitational potential energy.
