WebGravity is the weakest of nature’s four known fundamental forces, yet it is the most dominant force. Even though it is the weakest force, Gravity holds together the entire solar systems and galaxies. The free fall speed … Web1) The mass of an object can never be zero, but the weight of an object can be zero. a) True. b) False. Correct Option: (a) Explanation: When the net gravitational force acting on the object is zero, the weight of an object will become zero. But, since mass is a property of matter, the mass of an object can never be zero.
