After the Apollo 13 capsule swung around the Moon, the crew was able to speed up for the journey back to Earth by firing the Lunar Module (LM) descent engine. a.True b. False Which of the following is the most natural sleeping position in zero gravity? in a sleeping bag taped to any surface, with your arms floating out in front of your chest floating in mid-air with your legs straight and your arms straight at your sides flat on your back on the floor, with your arms resting on your chest curled in a fetal position, floating in mid-air
Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.
