Why do the astronauts appear weightless? In space their inertia becomes zero. They are falling at the same rate as the spacecraft. In space their mass becomes zero. They are outside of the earth's gravitational field. 2 / 5 2) In a laboratory on Earth, balances show that an object has a mass of 2 kg and a weight of 20 N. The same balances and object are then taken to the Moon. Are the mass and weight the same, or less than before? mass: sameweight: less mass: lessweight: same mass: sameweight: same mass: lessweight: less 3 / 5 3) A solid triangle made from copper is cut into three pieces P, Q and R. Which has the greatest density? piece P only pieces P and R only piece Q only all pieces have the same density 4 / 5 4) Which property of a block of metal remains constant when the metal is heated? density surface area volume mass 5 / 5 5) An object that has a mass of 15 kg on the Earth is taken to the Moon. The gravitational field strength on the Earth is 10 N/kg and on the Moon is 1.6 N/kg. What are the mass and the weight of the object on the Moon? mass: 15 kgweight: 150 N mass: 15 kgweight: 24 N mass: 24 kgweight: 15 N mass: 150 kgweight: 24 N Your score is Restart quiz
