Module Summary and Assessment
Module Summary and Assessment
The conservation of momentum is a fundamental principle of physics that can be used to predict the actions of colliding objects. We can use this information to design various types of safety equipment that reduce the amount of force acting on people experiencing a collision of some sort by increasing the time in which the force is experienced. Many devices such as helmets, air bags, and gymnastics mats operate on this principle.

Module Assessment
In this module you should have completed :
This is the last module in the unit. You should now be able to complete the unit 2 quiz and the unit 2 exam for the unit.
Unit 2 Conclusion
In this unit you have investigated Newton's first, second and third laws of motion as well as the law of conservation of motion. We have used our knowledge of these laws to discover the magnitude and direction of vector quantities for various scenarios including stopping distances. We also used displacement time graphs and velocity time graphs to discover information about moving objects using slope and area calculations.
