Newton’s Law of Universal Gravitation

SPH 4U

Where

is the force of gravity, in Newtons

is the gravitational constant,

equal to 6.67 x 10-11 Nm2/kg2

is the mass of object 1, in kilograms

is the mass of object 2, in kilograms

is the distance between the centres, in metres

- The mass of the earth is 5.98 x 1024 kg
- The radius of the earth is 6.371 x 106 m
These can be found on your formula sheet

The Red Bull Stratos jumper began his free fall 37000 m above the surface of the Earth. If his mass was 118 kg, what force of gravity did he experience as he left his vehicle?

Two students, each with a mass of 70 kg, are 1.5 m apart. Determine the force of gravity caused by each student.

- The strength of gravity at a given point in space
- The gravitational field strength can be found by:

Find the gravitational field strength on Saturn, if it has a radius of 6.03 x 107m and a mass of 5.69 x 1026 kg.
