An astronaut weighing 191 pounds on Earth is on a mission to the Moon and Mars. a) How much would it weigh in newtons when on the Moon? The acceleration due to gravity on the Moon is one sixth that of the Earth b) How much would it weigh in newtons when it is on Mars, where the acceleration due to gravity is 0.38 times that of Earth? c) What is its mass in kilograms on Earth? Which of the following is true? (Select all that apply) _Its mass on the Moon is exactly equal to its mass on Earth. _Its mass on the Moon is smaller than its mass on Earth. _Its mass on Mars is smaller than its mass on Earth. _Its mass on the Moon is greater than its mass on Earth. _Its mass on Mars is exactly equal to its mass on Earth. _Its mass on Mars is greater than its mass on Earth.
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.
