Section 1: Momentum and Impulse

Just a few Q’s What is your understanding of momentum? What factors cause an object to have momentum? If an object has momentum, what does that tell you about it?

Notes: Momentum: Momentum is like inertia in motion. Momentum = Mass x Velocity Or p = mv Problem: A .2kg baseball approaches the plate with a velocity 20m/s. Find its momentum.

What is impact???

Balloon Toss Demo: Get a partner and fill one balloon. Referrals to those who throw them at each other. 

Impulse: Change in momentum Derivation: When objects are stopped slowly….. When objects are stopped quickly….. (Demo: Desk Jump)

Sample Problem 1: Impulse b) Force to stop in .009s Find the following for a .5kg baseball when colliding with a wall and coming to a stop from 10m/s. Impulse b) Force to stop in .009s

Sample Problem 2: Find the following for the .5kg ball: a) Change in momentum b) Impulse c) Force to stop in .009s

Describe how to increase the impulse? (wood breaking demo)

Reduce the impact force, so don’t forget to wear your helmet!

Compression of a golf ball

Warm-up: Find the Impulse for Each Situation Warm-up: Find the Impulse for Each Situation. The mass of the car is 1000kg

Impulse Demos: Egg toss Chair Jump Balloon Toss

Find the total momentum before and after the collision 

Egg Launch Lab Objective: Wrap three eggs in a container so that when launched against a wall, they will not break. Grading: No eggs break- 20/20 1 egg breaks – 17/20 2 eggs break – 14/20 3 eggs break – 10 /20
