Impulse = change of momentum

J = ∫ SF(t) dt J = SFavg (Dt) J = area “under” a Force vs time graph J = Dp J = ∫ SF(t) dt J = SFavg (Dt) J = area “under” a Force vs time graph

Lab: Finding Mass of an Object Objective: Use the impulse – (change of) momentum theorem to compute the mass of an object Materials Diagram (labeled) Sketch of BOTH graphs for ONE trial, indicating how you got the data from the graphs Data / Analysis Table Sample Calculation of mass, average mass and percent error Conclusion (your answer, AND percent error)

The Egg Drop Objective: Protect a “naked” chicken egg that is dropped from heights of 1.0, 2.0 and 3.0m This will be contested on Monday December 5th The rules sheet will be posted on Schoolwires. Read it by Friday!
