  1. Practice Question Plants Aphids Spiders Sparrows In this food chain, the spiders are- A. Producers B. Primary consumers C. Competitors D. Secondary consumers D

  2. Conservation of Energy October 19, 2010

  3. Regular Energy Formulas • GPE= mgh • KE = ½ mv2 • Uspring= ½ kx2 • The potential energy of a spring

  4. Conservation of Energy Ei = Ef KEi + PEi = KEf + PEf ½ mvi2 + mgh = ½ mvf2 + mgh
