1. The gravitational force acting on an object is called its   weight   mass   momentum   density   Hint Half-n-half Clue   2. An object will weigh more at the poles than at the equator.   True   False   3. The approximate weight (on Earth) of a mass of 7 kg is   7000 N   700 N   0.7 N   70 N   Half-n-half Clue   4. The SI unit of momentum is   N s   Pa s   kg m/s2   N/s   Half-n-half Clue   5. When a force of 32 N acts on a body of mass 8 kg, the body will accelerate at   None of these   4 m/s2   32 m/s2   256 m/s2   Half-n-half Clue   6. A mass of 7 kg moves at 3 m/s.
