1. The SI unit of momentum is   Pa s   N/s   N s   kg m/s2   Hint Half-n-half Clue   2. The gravitational force acting on an object is called its   weight   momentum   density   mass   Half-n-half Clue   3. When a force of 14 N acts on a body of mass 7 kg, the body will accelerate at   98 m/s2   14 m/s2   None of these   2 m/s2   Half-n-half Clue   4. The approximate weight (on Earth) of a mass of 2 kg is   20 N   2000 N   200 N   0.2 N   Half-n-half Clue   5. A mass of 8 kg moves at 3 m/s. Its momentum is   24 kg m/s2   80 kg m/s2   80 N s   24 N s   Half-n-half Clue   6. Which is the odd one out?   momentum   force   acceleration   mass   Half-n-half Clue   7. If an object of mass 9 kg starts from rest and attains a velocity of 21 m/s after 7 s, then the force acting on it is   27 N   63 N   3 N   147 N   Half-n-half Clue
