Answer to Question 1

ANS: B
Energy that is stored or possessed by an object because of its position is called potential energy. Mechanical energy can be divided into either kinetic energy or potential energy. Chemical poten-tial energy often refers to the bonds in petroleum oils that, if broken, can be converted to kinetic energy.

Answer to Question 2

ANS: A
Kinetic energy = (mass of object  square of velocity it is traveling, or mv2) or KE = (V  V). If the velocity is reduced by half, then KE = (V  V), or () = reduction.
