Kinetic Energy Potential Energy Work None of the above All of the above KE and PE PE and WorkAs a steel beam is winched up to the top floor of a new building, the mechanical energy is being converted into what? 1 Thermal energy 2 Light energy 3 Kinetic energy 4 Potential energy
- A 5 kg ball and a 45 kg rock are dropped from the top of a 120 m cliff. Which object has more potential energy at the top of the cliffAs you learned in this course, there are many different energy transformations to accomplish the same tasks. The screen on your phone is actually an energy transformation technology. It converts electrical energy to radiant energy ight) There are many technologies which can be used to produce a screen, and their efficiency is linked in a complex manner to the colours in the image they display D Here is a simplified example: Power consumption Usable light output power Organic light emitting diode (OLED) 2.0 W 0.38 W Liquid crystal display (LCD) 3.0 W 0.25 WTwo cars come to a stop from the same initial speed, one braking gently and the other braking hard. Which car converts more kinetic energy to thermal energy? The gently braking car The hard braking car Both cars convert the same amount of kinetic energy to thermal energy
