  1. 1. 1. Which picture below illustrates the concept of energy transformation? 2. Which picture below illustrates the concept of energy transfer? 3. In picture A, the total energy before the collision the total energy after the collision. A. is less than B. is greater than C. is equal to 4. In picture B, the total energy before the car stops the total energy after the car stops. A. is less than B. is greater than C. is equal to A B B A
