In this segment we define the terms momentum and impulse. We see the impulse-momentum theorem in action by analyzing the motion of a freerunner and the motion of an egg hitting two very different surfaces.
Segment 4A: Momentum and Impulse We define the terms momentum and impulse. We see the impulse-momentum theorem in action by analyzing the motion of a free runner and the motion of an egg hitting two very different surfaces.Premiere Date: July 24, 2018 | Runtime: 00:05:04
-Define key terms, including momentum and impulse.
-Explain that momentum is a vector quantity and the direction matters.
-Explain how an object’s change in momentum depends on the net force it experiences and the length of time the force is applied.
-Define impulse and how it relates to momentum through the impulse-momentum theorem.
-Discuss the real-life implications of manipulating variables within the impulse-momentum theorem.
impulse (I) - the product of the force acting on an object over the time during which the force acts.
impulse-momentum theorem - this theorem states that the impulse applied to an object is equal to the change in momentum of an object.
momentum (p) - the quantity of motion of an object or, mass in motion; momentum is calculated by multiplying the mass of an object by the velocity of an object.
The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study. GPB offers the teacher toolkit at no cost to Georgia educators. It will be available in September 2018. To preorder your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units of study.
