Answer the following question given this paragraph: One force acting on youand all the other objects on Earthis gravity. Look at the physics book in the Figure below . Gravity pulls the book downward with a force of 20 Newtons. Why doesn't the book fall to the ground? The table pushes upward on the book with the same amount of force. The combined force, or net force , acting on the book is 0 Newtons. That's because upward and downward forces are balanced, so they cancel out. You can learn more about net force at this URL:. Q: The pull of gravity is expressed as a force of what? Choices: - joule - pascal - volt - newtons A:
A:
newtons
