Why does a book on a table not move?

• No forces are acting on the book
• Gravity is the only force acting on the book
• Forces of the table pushing up and gravity pulling down are balanced

If you go to the moon ...

• your mass changes, but your weight stays the same

• your weight changes, but your mass stays the same

• both your mass and weight change

• both your weight and mass stay the same

What is "net force"

• the total amount of force acting on an object

• half of the force acting on an object
