Question:
If an object is in free fall (with no air resistance)
for 4 seconds, this will be it’s velocity at the end
of the 4 seconds.
Answer:
What is v=g*t
= 9.8 m/s2 * 4 s
= 39.2 m/s

This force remains the same on a skydiver from
the time they leave the plane until they touch
the ground.
Answer:
What is gravity?
Miscellaneous: 1000
Question:
This is why moons stay in orbit around planets.
Answer:
What is the moons are free falling towards the
planet while moving forward at the same time.
This results in a curved path which is the same
as the curve of the planet.
