### Conservation of Energy and Momentum

Broad Concept: The laws of conservation of energy and momentum provide alternate approaches to predict and describe the movement of objects.

 2.1 Interpret and provide examples that illustrate the law of conservation of energy. * 2.2 Provide examples of how energy can be transformed from kinetic to potential and vice versa. 2.3 Apply quantitatively the law of conservation of mechanical energy to simple systems. 2.4 Describe the relationship among energy, work, and power both conceptually and quantitatively. 2.5 Interpret the law of conservation of momentum and provide examples that illustrate it. Calculate the momentum of an object. 2.6 Identify appropriate standard international units of measurement for energy, work, power, and momentum.
