Explain everything you know about acceleration. Include definitions, formulas, and examples. Some of the points I will be looking for include: free fall, circular motion, direction changes, and the difference between speed and acceleration.

the surroundings, what is the specific heat of the metal?

B. Which is more useful for storing thermal energy: this metal or an equal weight of water? Explain.

C. If the heat absorbed by the Styrofoam actually is not negligible, how would the specific heat you calculated in part (a) be in error? Would it be too large, too small, or still correct? Explain.
