Newton s law of universal gravitation

Newton’s Law of Universal Gravitation

SPH 4U


Newton s law of universal gravitation1

Newton’s Law of Universal Gravitation

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


Important things to remember

Important Things to Remember

  • 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


Example 1

Example 1:

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?


Example 2

Example 2:

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


Gravitational field strength

Gravitational Field Strength

  • The strength of gravity at a given point in space

  • The gravitational field strength can be found by:


Example 3

Example 3:

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.
