Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
The gravitational potential energy of mass m at distance r from mass M is
GMm/r
−GMm/r2
−GMm/r
GMm/r2
2.
The mass of a probe is doubled while all else is unchanged. Its gravitational potential energy at a given distance
doubles
halves
stays the same
quadruples
3.
At infinite separation the gravitational potential energy is
maximum negative
zero
infinite
equal to mg
4.
The gradient of an Ep–r graph at a point gives
the field strength
the potential
the magnitude of the gravitational force
the kinetic energy
5.
A 2.0 kg mass is at r = 2.0 × 107 m from the Earth's centre (GM = 4.0 × 1014). Its Ep is
+4.0 × 107 J
−2.0 × 107 J
−8.0 × 1014 J
−4.0 × 107 J
6.
For a mass thrown up from the surface, using ½v2 = gh instead of the full energy equation gives a maximum height that is
too large for large speeds
too small for large speeds
the same
exactly half
