A man is riding a loop-the-loop type roller coaster, and he is sitting on a spring scale as the car moves. The car rolls freely on the circular track, and thus moves fastest at the bottom of the loop and slowest at the top. A B C D In which position of the car and man is the reading of the spring scale largest

the device is called “ rocket engine”

are you like autistic or something?

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

total distance/total time

(85 + 82)/(5+3)
