Better titles now! :D Found these online, princess001, hope they help.

1. How is momentum related to Newton's laws? (2 marks)

Newton’s second law explains that the external, non-zero, net force acting on an object will be equal to the rate of change of the momentum of that object. This has particular relevance to situations involving large changes in momentum, such as those of vehicle collisions that occur at a high rate of speed.

2. How is impulse related to Newton's laws? ( 2marks)

By applying Newton’s second law, impulse can be described in terms of a change in velocity, caused by a non-zero (unbalanced) net force.

Impulse may also be represented graphically in the form of a force-time graph. In such cases, the product of force and time, or the impulse, is represented by the area of the graph.
