Question 8

What is the raisin cake model intended to explain about the expansion of the universe?

Answer 8

Every raisin in a raisin cake moves farther away from every other raisin: there is no special center raisin ( and no special central galaxy )

Question 9

The star of Betelgeuse is about 425 light years away. If it explodes tonight in an extremely bright supernova explosion …

Answer 9

We won’t know about it until 425 years from now

Question 10

Kepler 1 st law

Answer 10

The orbit of each planet is an eclipse with the sun at one focus

Question 11

Kepler 2nd law

Answer 11

A planet moves in its orbit it sweeps out equal areas in equal times

Basically speed = distance/ time

S=D/T

Question 12

Kepler 3rd law

Answer 12

Distant planets take more time to orbit
More distant planets orbit at slower average speeds

Basically

1. The size and geometry of each planets orbital path
2. The speed of each planet along its path at each time

Question 13

Transits

Answer 13

When a planet passes between us and the sun like an eclipse

Question 14

Prograde

Answer 14

Drift West to East

Question 15

Retrograde

Answer 15

Moves the other way

East to West

Question 16

What’s the cause of retrograde?

Answer 16

As the planets orbit the sun the outer planets move more slowly than the inner planets
( Keplers Law )

Question 17

Galileo

Answer 17

Galileos telescope observations of planets and moons

Question 18

What is Issac Newton 1st law?

Answer 18

An object moves at constant velocity if there is no net force acting upon it

Question 19

What is newton 2nd law?

Answer 19

The acceleration of an object is that objects net force applied divided by the mass

Force= mass x acceleration

Question 20

What is newton 3rd law ?

Answer 20

For any force, there is always an equal and opposite reaction force
