The atoms in a solid move about freely
Answers
No, not exactly. They jiggle and tremble and vibrate a lot, but
they always basically stay in very nearly the same place.
It's like if you're allowed to go anywhere you want in your jail cell,
you wouldn't exactly call that "moving about freely".

Final answer:
Gravity is present when a block hangs at rest from a piece of rope. The block remains in equilibrium, suspended by the tension in the rope which is equal and opposite to the gravitational force acting on the block.
Explanation:
In the scenario where a block hangs at rest from the ceiling by a piece of rope, gravity is indeed present. The force of gravity, often referred to as weight, acts downwards on the block. However, the block is not falling because there is an equal and opposite upward force - this is the tension in the rope. According to Newton's second law, the tension in the rope must be equal to the weight of the block for it to remain in equilibrium and not move. The tension in the rope and the gravitational force on the block are equal in magnitude but opposite in direction, which sums up to zero net force, hence the block is at rest.
