Momentum, Impulse, and Collisions A.S. 2.4.1 – 2.4.6 Due Monday, January 12 Quiz covering Momentum, Impulse, and Collisions on Monday, January 12
3
Introductory Examples… Work with your table group You will be assigned one of the following of activities: 1. Landing after a ski jump so you do not hurt your knees 2. Catching a water balloon so you do not get wet 3. Catching an egg so you do not get yolk-y 4. Jumping off a lab station without hurting your knees 5. Catching a 90 mph fastball (baseball) without breaking your hand 6. A stunt performer jumping off a three story building without getting hurt On your whiteboards, explain and illustrate how you would instinctively perform the assigned task. You have 4 minutes. Go!

Stop what you’re doing! Time to share out your creations! One person from each group bring your whiteboard to the front of the room and hold it high! Are there ANY similarities to the descriptions and/or the illustrations for all the scenarios?
11
Momentum Used to quantify the motion of a mass Mathematical definition: Momentum is equivalent to the product of an object’s mass (in kg) and its velocity (in m·s -1 ). Momentum IS a vector quantity
12
Fun Facts You Should Remember About MOMENTUM!
13
Whiteboard problem!
14
What is its change in kinetic energy?
15
Impulse
16
Impulse—video demonstrations For each demonstration shown and discussed, think about the following: WHAT was causing the change in momentum? HOW was the applied force changed?
