In this module, you applied the principle of conservation of energy to understand the transfer of potential energy to kinetic energy for a skateboard on a half-pipe. provide an example from your experiences of a situation where the potential energy of an object transferred to kinetic energy and then back to potential energy. describe what happens to the total amount of energy during the situation (increase, decrease, stay the same) and explain how you know this. question 10 options:

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
