1. An object is moving in a circular path. The force acting on the object towards the center of the circle is called the   centripetal force   magnetic force   gravitational force   centrifugal force   Hint Half-n-half Clue   2. The SI unit of force is   dyne   newton   joule   pascal   Half-n-half Clue   3. Momentum is defined as   mass × velocity   mass × acceleration   mass × velocity2   force × distance   Half-n-half Clue   4. "A body continues in its state of rest or uniform motion in a straight line unless acted upon by a force" is a statement of   Newton's first law of motion   Newton's second law of motion   Newton's law of gravitation   Newton's third law of motion   Half-n-half Clue   5. The SI unit of momentum is   N s   N/s   kg m/s2   Pa s   Half-n-half Clue   6. The rate of change of _______ is due to forces applied.   acceleration   velocity   momentum   displacement   Half-n-half Clue   7. If an object of mass 8 kg starts from rest and attains a velocity of 18 m/s after 6 s, then the force acting on it is   24 N   108 N   3 N   48 N   Half-n-half Clue
