Ostension: is the pointing to objects for the purpose of definition or description. A known problem is the indeterminacy or lack of uniqueness of the reference in pointing. For example, an object, its form, its nature, its history, its weight, etc., can be meant. See also Gavagai, pointing, to mean, indicative definition, definition, definability, statue/sound.

Showing/Evidence/Feynman: what actually means "show that something is true"? We find out directly from Newton's law that the kinetic energy should change when we form its derivative by time, and then apply Newton's law.

dT/dt = d/dt(1/2mv²) = 1/2m2v (dv/dt) = mv (dv/dt)

From the 2nd Newtonian law, however, follows m(dv/dt) = F such that

dT/dt = Fv.

in the one-dimensional case, it is force times speed.
