Warm up 04-30-14 • Question: Friction transforms mechanical energy into ____ energy. • Answer: • Thermal • Goal: I will master conservation of energy problems.
Element of the day • 99 – Einsteinium – Es • Einstein is one of over 800 Nobel prize winners, but his place in history is even more elite for having an element named after him. • Einstein is credited for having written a letter to president Franklin D. Roosevelt cautioning him on the destructive power of the atomic bomb, but actually the letter was drafted by a friend who first realized the potential for destruction from a nuclear chain reaction (a neutron splits the nucleus of another atom, which releases energy and more neutrons that go on to split other atoms).
