Can I improve the design of my simple machine? How? The steps required to design my simple machine
1. I Got some Clay and 2 bottle caps for the axle and wheels, respectively.
2. I rolled the clay into a stick
3. Next I put some clay in the Bottle caps
4. After that, I stuck the clay in the bottle caps to the clay stick
5. Then, My DIY Wheel and Axle was ready!

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.

it is b. absorbs thermal energy
