This document contains a trial exam on the conservation of energy with multiple choice and free response questions. The multiple choice section covers concepts like work, potential energy, kinetic energy, efficiency, and power in problems involving crates being pushed, statues being raised, buckets being lifted, horses pulling wagons, cars accelerating, and people swinging. The free response section asks students to identify key terms like work, power, kinetic energy, and the work-energy theorem. It also provides word problems to solve using concepts of springs, collisions, roller coasters, and objects attached to springs.
