Sheet-Investigation 2
A friend at another school sends you an email. In that
email your friend tells you that they are studying the
solar system in science class. Your friend is confused
about gravity.
They read in a science book that gravity is a force that
keeps planets in orbit around the Sun. But your friend
thought that gravity is the force that pulls things toward
the center of Earth. For example, when you drop a bail,
it falls down to the ground.
Your friend asked this question. Is it possible that both
these things could be true about gravity?
Write a reply to your friend. What would you tell your
friend to help him or her answer this question?
