These are the two factors that determine gravity.
The names of the four outer planets in order.
What are Jupiter, Saturn, Uranus and Neptune
The time it takes for the I.S.S. to orbit planet Earth (about 16 times per day).
What is 90 minutes?
This is the reason we experience seasons.
What is the Earth's axis (tilt)?
This is the law that says the amount force needed to move an object any distance depends on its mass. It is written as F=ma

What are the polar regions?
This law states that for every action, there is an equal and opposite reaction.

What is a collision?
This takes into account not only how fast something is traveling, but its mass and direction.
What is momentum?

What is Mercury and Neptune?
He holds the record for the longest single spaceflight.
Who is Scott Kelly?
This is the time that it takes for Earth to orbit the Sun.
What is one year (365 days)?
Parachutes work by slowing this down which reduces the amount of energy transferred during a collision.
What is momentum?
