Question

A block falls from a ledge 10 m high. Just before it hits the ground, its kinetic energy is......

a. equal to its potential energy at that point.
b. equal to zero.
c. increasing.
d. equal to its potential energy on the ledge.
e. all converted into thermal energy.
f. the same as on the ledge.

Answer 1

It would be D because the potential energy converts to kinetic energy on the way down. Hope it helped. :)

Answer 2

I would say D because an object's potential energy turns into kinetic energy as it falls.
