1
Objective Writing very large and very small numbers in standard form

2
DATA Very large numbers such as: 4 504 000 000 Are not very practical to use in calculations so we can rewrite it like this:

3
4 504 000 000 4.504 x 10 9 Number between 1 and 10 Power of 10

4
Write all of the distances from the sun in standard form

6
Write all of the planets masses as normal numbers

8
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 planets surface. This speed, known as the ESCAPE VELOCITY, depends on both the radius of the planet, and its mass G = Gravitational Constant 0.000 000 000 0667 M = Mass of the planet (in kg) R = Radius of the planet (in m)

9
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:

10
0.000 000 000 06 67 6.67 x 10 -11 Number between 1 and 10 Power of 10

11
Calculate the escape velocity for each of the planets

12
G = 0.000 000 000 0667

OK

The “space” between objects in space is so large that normal units of measurement don’t work; for example the sun is 93,000,000,000,000 miles away from.
