Physicists sometimes hypothesize the existence of the "gravitron". This would be a particle responsiible for the force of gravity. Would you expect the gravitron to be a part of the standard model for physics? a .Yes, because the standard model describes all the fundamental forces like gravity.

b. No, because the standard model does not include particles in the discussion.

c. Yes, because the standard model describes the effect of gravity on particles.

d. No, because the standard model describes only the fundamental forces other than gravity.

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.
