Electric Forces. ... Just like objects that have mass exert gravitational forces on each other, objects that are charged will also exert electric forces on each other. The electric force is directly proportional to the charge of the two objects and inversely proportional to the distance between them squared.
Answer:
It allows us to understand nature much more deeply than does qualitative description alone.
Explanation:
Without explaining the measurements, a quantity cannot always be measured.

I believe the answer would be Kinetic Energy. Kinetic energy is defined as energy which a body possesses by virtue of being in motion. We weren’t given answer choices so I don’t have much to work with lol.
-- Energy is never created or destroyed.
-- No energy is added to the pendulum during its swing.
-- If we ignore air resistance and friction, then no energy is lost
from the pendulum during its swing.
-- Therefore the total energy of the pendulum must be constant.
-- Any potential energy lost at any point in the swing
must show up as kinetic energy. If it had 484J at the top,
then it'll have 484J at the bottom.
