ObjectiveWriting very large

and very small numbers in

standard form

DATA

Very large numbers such as:

4 504 000 000Are not very practical to use in calculations so we can rewrite it like this:

4 504 000 000

4 .504x 109Number between 1

and 10Power of 10

Write all of the

distances from the

sun in standard

form

Write all of the planets’ masses as

normal numbers

The gravitational pull of each of the planets in the Solar System is different and this will affect the velocity that a spacecraft would need to be travelling to leave the planet’s surface. This speed, known as the ESCAPE VELOCITY, depends on both the radius of the planet, and its mass

RGM2

G = Gravitational Constant 0.000 000 000 0667 M = Mass of the planet (in kg)R = Radius of the planet (in m)

DATA

Very small numbers such as:

0.000 000 000 0667

Are not very practical to use in calculations so we can rewrite it like this:

0.000 000 000 06 676.67x

10-11Number between 1 and 10

Power of 10

Calculate the escape velocity for each of the

planets
