Choose the appropriate word choices below that correctly complete the blanks in the following three sentences: left: at the beginning, the object is at the origin and the object is moving to the slowing down: at first, the object is positive: due to a acceleration. right: in the second part of the motion, the object is moving to the speeding up: and /left-speeding up/slowing down/staying the same-positive/negative/zero-right/l eft-speeding up/slowing down/staying the same

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.
