I can calculate my velocity as we enter Earth's orbit by using this formula; v=u-gt. Let's calculate the velocity of the spaceship after 1 minute together before we head back down to Earth.
And because there's no air, the only force acting on me is the gravity from the sun that keeps us in orbit. That means I'm technically in free-fall!
I'm about to go back to Earth. When we enter Earth's orbit, gravity will act upon us at a rate of 9.8m/s. If we neglect the atmosphere and air resistance, we would be entering Earth in a free-fall!
Let's name some examples of free-fall together, neglecting air resistance on Earth. Yes, that's right! Dropping a ball, and skydiving are both examples of free-fall when neglecting air resistance. Well done!
