Lesson 19 portfolio answers: 100% 1. A) chemical potential energy b) Efficiency (% efficiency) c) Elastic d) Electrical energy e) Energy f) Electric generators g) Gravitational potential energy h) Hybrid vehicle i) Kinetic energy j) Law of conservation of energy by k) Non-renewable natural resource l) Nuclear energy m) Power n) Radiant o) Renewable p) Sound q) Sustainable energy r)Technology * s) Thermal t) The law of conservation of energy * u) Transformation of energy v) The first law of thermodynamics * 2. A. a) The area of the smaller cylinder decreases for the rows number 1,2,3. It remains constant in the last three rows b) The area of the larger cylinder stays constant while the smaller cylinder’s area changes in the first three rows. This can imply that any change in FL (force applied to the large cylinder) is due to changes in AS ( Area of small cylinder) in the first three rows. c) As AS (area of small cylinder) decreases, FL and MA both increase. d) You can increase F L in a braking system by decreasing
