Consider a system composed of a block sliding on an inclined plane in relation to the horizontal direction, where there is no friction between the block and the plane. Only the weight forces and the force that the plane exerts on the block act on the block. This same system (inclined plane+block) can be placed on the surface of the Earth or the Moon. Which statements are correct: I - The acceleration of the block when the system is on the surface of the Moon is lower than when it is on the surface of the Earth. II - The inertial mass of the block is smaller on the Moon than on Earth. III - The normal force vector on the block will point in the same direction both when the system is on the Earth's surface and when it is on the Moon's surface. a) Only statement I. b) Statements I and III. c) Statements II and III. d) Statements I and II. e) All statements are correct. f) Only statement II. g) No statement is correct. h) Only statement III.
