Force due to
gravity
Ratio of the
weight to the
Gravitational
mass of an object field strength, g.
(Fg/m)
The weight of an
object is the
force due to
gravity acting on
it (true or false?)
True
An object
revolving around
Earth or another
planet
satellite
The gravitational
field strength is
the ratio of the
mass to the
weight of the
object (True or
False?)
False

In SHM max Ek
occurs when
object passes
through
equilibrium point
Has a value equal
to the amplitude
of the SHM
In SHM max Ep
occurs when
object is at the
