At position B, just before the collision, the ball's gravitational potential energy is zero and the kinetic energy is ½ m1v1i 2. Using conservation of energy, m1gh = ½ m1v1i 2. and = 14 m.s-1. The collision is inelastic so we cannot use conservation of mechanical energy, but momentum is still conserved.

15.1 Energy Conservation: Foundation of a Sustainable Energy System. Energy is used wastefully in virtually all nations. Excessive waste is a sign of an unsustainable technology. Economic and Environmental Benefits of Energy Conservation. Energy-efficiency measures can reduce the world’s dependence on fossil fuels.

Clearly state the difference between energy efficiency and energy conservation. Conduct a home energy audit. Identify ways to save energy in the home, either through energy efficiency or energy conservation. Class Time: 20 minutes pre-lab in class. 50 minutes to conduct the audit as homework. 30 minutes post-discussion in class.
