2nd Law of Acceleration
3rd Law of Action-Reaction
I did not pay attention to the Google Quiz last Friday
Which of these has more inertia: a 0.02 kg ball or a 10 kg box?
The box because it has more mass.
The ball because it has less mass.
Both have the same inertia.

A book weighs 10 N on Earth. Which of the following statements is TRUE about the same book on the Moon, where g = 1.67 m/s2?
The book would weigh less on the Moon.
The book would have less mass on the Moon.
The book would have more mass on the Moon.
The book would weigh more on the Moon.
A book weighs 10 N on Earth. Which of the following statements is TRUE about the same book on the Moon, where g = 1.67 m/s2?
The book would have less mass on the Moon.
The book would have more mass on the Moon.
The book would weigh more on the Moon.
The book has the same mass because mass is constant.
