Compare and contrast gravitational force and strong nuclear force. describe at least two ways that they are alike and two ways that they are different.

Gravitational force is the force of attraction of different bodies due to their masses.

Nuclear force is the force that acts between protons and neutrons of atoms.

Different:

Strong nuclear force applies only to protons while gravity applies to all matter.

Gravity occurs on all the levels of space while the strong nuclear force occurs only at the sub-atomic level.

Alike:

They are both attractive forces.

They are both charge-independent.
