1.
To calculate each planet’s acceleration of gravity
Earth’s acceleration of gravity x Gravity Multiplier
2.
To calculate your mass in kilograms, 1 kg = 2.2 pounds, so mass in kilograms = ______(body mass in lbs)______ ÷ 2.2 lbs
3.
To calculate your “New” weight in kilograms =
Mass (kg) x Gravity Multiplier
4.
To calculate your “new” weight in Newtons = Mass (kg) x acceleration of gravity (m/s 2 )
5.
To calculate your “new” weight in Pounds = “new” weight (kg) x 2.2

1. Does your mass change depending on which planet you are on? Why or why not?
2. In physics sense, when a person goes on a diet, do they lose weight or mass? Explain your answer?
3. The general rule of thumb is that you will weigh ____________________ on planets larger than Earth, and weigh ____________________ on planets smaller than Earth.
4. What is a really easy way to lose weight without losing mass?
5.If scientists for some reason wanted to visit Kepler-22b, what would be some health concerns they would want to warn people about? Cite evidence from the reading article.
6. If scientists for some reason wanted to visit Kepler-10c, what would be some health concerns they would want to warn people about? Cite evidence from the reading article.
7. NASA has a zero-gravity training plane in which astronauts and ordinary citizens can ride in to experience zero gravity or weightlessness for 20-30 seconds at a time. Use the graph below to explain why people would feel weightless.
