6.1 Gravitational Forces and Fields
- 6.1.1
- Newton's universal law of gravitation
- "Every single point mass attracts every other point mass with a
force that is directly proportional to the product of their masses
and inversely proportional to the square of their separation"
- This means that there is a
gravitational force between all
masses in the universe. This
force is bigger if the bodies
are heavier and if they are
closer together than if they
are small and far apart
- This means that there is a

- Newton's universal law of gravitation
- 6.1.2
- Gravitational field strength, g
- a measure of how much force a body will
experience in a gravitational field
- g= F/m
- Added vectorically
- g= F/m
- a measure of how much force a body will
experience in a gravitational field
- Gravitational field strength, g
