         8        Newton’s third law of motion can be premising used to explain:                                   1
                         (a) Running and jump                        (b) Sitting and standing
                         (c) Rolling sliding                             (d) Lay & sleeping

         9        What is the formula used for Newton’s second law of motion?                                      1
                         a) Velocity = acceleration x time           (b) Force = Mass × acceleration
                         (c) Momentum = mass × volume                (d) Speed = distance/time

         10       Which one of the following is not the Law of Motion?                                             1
                      A-  Law of Inertia.   B- Law of Reaction.   C- Law of Readiness. D- Law of
                         Acceleration.

         11       What do you mean by sports Biomechanics?                                                         3
         12       Why is friction necessary for movement?                                                          3
         13       Friction opposes the motion of one body over the others. How it is useful in sports?             3
         14       Explain the methods to reduce friction in sports.                                                3
         15       How can bio-mechanics help in the field of sports? Give your view on this                        3
