- A concentrated mass resulting from gravitational collapse near
which gravity is so strong not even light can escape is called
a
].
- The ratio of the output energy for a machine to the total input
energy is called
the
of the machine.
- “For any pair of objects, each body attracts the other with a
force that is directly proportional to the product of their masses
and inversely proportional to the square of the distance between
their centers of mass.” This is a statement
of
.
-
is
the rate at which work is done or energy is transformed:
work/time.
-
is
the number of rotations per unit time.
- The product of the force and the lever arm on a body which
imparts a rotational acceleration on the object is
called
.
7. The force of an object on a surface, usually due to gravity,
is called
