gravitational force

The weakest of the four fundamental forces of nature, being the attractive force that arises from gravitational interaction. Newton's law of gravity states that the gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Based on the data, the team, with the participation of the China Earthquake Administration and the University of the CAS, found that gravitational force released from the sun and gravitational force recorded at ground stations on Earth did not travel at the same speed, with the time difference exactly the same as the time it takes for light to travel from the sun to observation stations on Earth.

Scientists find evidence for speed of gravity

The sense of the object as vulnerable to gravitational force is palpable, recalling Morris's assertion that "one of the conditions of knowing an object is supplied by the sensing of the gravitational force acting upon it in actual space." Furthermore, Double Prop invites us to grapple with its components--nearly everything in the sculpture is a prosthetic device or tool for the human body--as we imagine the artist having done in the work's assembly.
