1. The gravitational force acting on an object is called its   weight   density   momentum   mass   Hint Half-n-half Clue   2. If an object of mass 8 kg starts from rest and attains a velocity of 21 m/s after 7 s, then the force acting on it is   147 N   56 N   3 N   24 N   Half-n-half Clue   3. Force is defined as   mass / volume   mass × acceleration   mass × velocity   pressure / area   Half-n-half Clue   4. When a force of 32 N acts on a body of mass 8 kg, the body will accelerate at   4 m/s2   256 m/s2   32 m/s2   None of these   Half-n-half Clue   5. One newton approximately equals the force of gravity acting on an object of 1000 grams.   True   False   6. The SI unit of force is   dyne   joule   pascal   newton   Half-n-half Clue   7. An object will weigh more at the poles than at the equator.   True   False
