Lesson Summary

 

In this lesson you explored the following essential questions:

• What is impulse?
  
  

• How is impulse related to a change in momentum?
  
  

• How is impulse used in the design of safety devices that protect the occupants of vehicles during a crash?

Impulse is the product of the net force applied to an object and the time interval during an interaction. Newton's second law can be used to demonstrate that the impulse applied to an object is equivalent to the change in the momentum of that object.

 

 

In the design of many safety devices, the force providing the impulse to an object or a person can be minimized if the time interval through which the force acts is maximized.

impulse: the product of the net force applied to an object and the time interval during an interaction

 

The equation is as follows:
