Last Problem:
Do astronauts on the moon weigh the same as they do on the earth?
Answer:
No.
The surface of the moon’s gravitational pull is approximately one-sixth (1/6) that of the earth’s gravitational pull. This means astronauts on the moon will weigh 1/6th of what they will weigh when they are earth bound.
Today’s Problem:
A large stone is 100 times heavier than a small stone, but when dropped at the same time, they fall with the same acceleration (ignoring air resistance). This is a lesson we all learned in 5th grade.
Why doesn’t the large stone accelerate faster? Is it because of its weight, its energy, its surface area or its inertia perhaps?
