Go over Newton's 3rd Law test.

Introduction to impulse and momentum lesson

Content Objectives:
Student will be able to
. Define impulse and momentum
. Give the correct units for impulse and momentum
. Calculate impulse and momentum
. State that impulse = change in momentum
. Describe several real-life examples using impulse = change in momentum
. Explain why impulse is greater in bouncing than in sticking

Handed out RA 5.1 due Tuesday
Assigned Quia Quiz 5.1-15 Random - REQUIRED QUIZ - do by Wed and get 100% correct
Also put up full quiz with all questions.

Impulse = Fnet*time
Units of impulse = N s

Momentum = mass * velocity = inertia in motion = ooomph
Units of momentum = kg m/s

Derived Impulse = Change in momentum

Several examples of F*t for same change in momentum
