1) What is mass? a) Amount of matter contained in a unit volume of a body. b) Amount of matter contained in a body. c) The pull of gravity contained in a body. d) Number of particles contained in a substance. 2) Which one is not true about the differences between figure A and figure B in the insert. a)  Figure A is beam balance while figure B is spring balance. b) Figure A measures mass while figure B measures weight. c) The quantity measured by figure A changes from place to place while that measured by figure B does not change from place to place. d) SI unit of the quantity measured by instrument in figure A is Kg while that measured by instrument in figure B is Newton. 3) ..................describes the pull of gravity on a body? a) Weight b) Mass c) Force d) Inertia 4) Why does the weight of the same mass of object change as it moves from Earth to moon? a) Because mass of an object on the moon is less than that on Earth. b) Because the moon is very far away from the Earth. c) Because the moon gives off light while the Earth does not. d) Because gravity on the moon is less than that on Earth. 5) What is the relationship between mass and weight? a) Weight increases with increasing mass. b) Weight decreases with increasing mass. c) Weight remains constant as mass increases. d) Weight increases as mass remains constant. 6) One of the following is not true about the differences between mass and weight, which one is it? a) Mass is amount of matter while weight is pull of gravity. b) Instrument of mass is beam balance while that of weight is spring balance. c) SI - unit of mass is kilogram while that of weight is Newton.   d) Mass is derived quantity while weight is basic quantity. 7) How is mass similar to weight? a) Both mass and weight change with the quantity of matter. b) Both mass and weight are measured using the same instrument. c) Both mass and weight have the same SI - unit. d) Both mass and weight change from place to place. 8) Why does weight keep on changing from place to place? a) Because it is measured by spring balance. b) Because gravity differs from place to place. c) Because it has direction. d) Because its mass also changes from place to place. 9) The reason why mass does not change from place to place is....... a) because the amount of matter in a body is fixed. b) because gravity changes with mass c) because mass lacks wear and tear. d) because the instruments of mass never change. 10) A stone of mass 50Kg is moved from the Earth where acceleration due to gravity is 10N/Kg to the moon where acceleration due to gravity is 6 times smaller than that on earth. What is the new mass of the stone on the moon? a) 0.5Kg b) 5Kg c) 50Kg d) 500Kg
