	2. Conservation of Energy and Momentum	MCAS Questions

	The chemical of the energy in the food eaten by these rowers becomes forward motion, motion of the water, and heat. All energy is conserved.
	Broad Concept: The laws of conservation of energy and momentum provide alternate approaches to predict and describe the movement of objects.	2006-14
	2.1 Interpret and provide examples that illustrate the law of conservation of energy.	2006-14
	2.2 Interpret and provide examples of how energy can be converted from gravitational potential energy to kinetic energy and vice versa.	2006-24 2006-31 2006-44 2005-8 (Open-Response Question) 2004-17 Printable Summary List
	2.3 Describe both qualitatively and quantitatively how work can be expressed as a change in mechanical energy.	2006-36 2004-2 Printable Summary List
	2.4 Describe both qualitatively and quantitatively the concept of power as work done per unit time.	2006-17 2005-21 2004-12 Printable Summary List
	2.5 Provide and interpret examples showing that linear momentum is the product of mass and velocity, and is always conserved (law of conservation of momentum). Calculate the momentum of an object.	2006-20 2006-26 2006-43 2005-19 2004-4 2004-20 Printable Summary List
