The APsolute RecAP: Physics 1 Edition - Mechanical Energy Types and Conservation of Energy
Description
Enjoy your roller coaster ride in Episode 15! Roller coasters are excellent examples of the law of conservation of energy in action. (1:17 ). Visualize the change in mechanical energy type using a bar graph (2:05 ). We know that the law of conservation of energy states that unless there was external work done on the earth-coaster system, then the total mechanical energy is constant. (2:54 ) Finally, calculate power, which is how quickly work can be done or how quickly energy is changed. (7:06 )
The Question of the Day asks: (8:26 ) If a roller coaster is located at a position ⅓ as high as the tallest drop (h), using variables only, what would the speed (v) be?
