Lesson 2 | Energy Transfers and Transformations



Energy Transfers and Transformations

Key Concept How is energy transformed and transferred?

Directions: Put a check mark in the column that describes each example. Then identify the type of energy being

transferred or transformed. (Hint: For transferred energy, you will only need to identify the type of energy being

transferred. For transformed energy, you will need to identify the initial energy and the new type of energy after the

transformation.)
