Physics Name ___________________________ Period ____ Date ___________________ Astronaut Physics Directions: Answer the following items. complete many of the items. 1. In your protective space suit, you have a mass of 120 kg (264 lbs). What is your weight (in Newtons) on every planet? Planet Acceleration due to gravity Weight (N) 3.6 m/s2 8.8 m/s2 9.8 m/s2 3.8 m/s2 26.0 m/s2 11.2 m/s2 10.5 m/s2 13.3 m/s2 Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune 2. You will likely need a calculator to On your science expedition you are asked to retrieve 1000 N of soil from each planet. What is the mass of each sample you will retrieve? Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Weight of Soil Acceleration due to gravity 1 000 N 1 000 N 1 000 N 1 000 N 1 000 N 1 000 N 1 000 N 1 000 N 3.6 m/s2 8.8 m/s2 9.8 m/s2 3.8 m/s2 26.0 m/s2 11.2 m/s2 10.5 m/s2 13.3 m/s2 Mass (kg) 3. On which planet will the gravity feel most like Earth? 4. On which planet will you have to exert the most force to move around? 5. On which planet will you have to exert the least amount of force to move around? 6. During your free time, you enjoy playing basketball on other planets? Why are the rims on Mars 25 ft. in the air? 7. During another experiment, you have to drop an object for 5 seconds and measure its instantaneous velocity. How fast will an object be traveling after 5 seconds of free-fall on each planet? Use the equation vf = vi – gt Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Acceleration due to gravity Velocity (m/s) 3.6 m/s2 8.8 m/s2 9.8 m/s2 3.8 m/s2 26.0 m/s2 11.2 m/s2 10.5 m/s2 13.3 m/s2 8. You must also measure how far an object will travel during 5 seconds of free-fall. Use the equation d = vit – ½gt2 Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Acceleration due to gravity Distance (m) 3.6 m/s2 8.8 m/s2 9.8 m/s2 3.8 m/s2 26.0 m/s2 11.2 m/s2 10.5 m/s2 13.3 m/s2 9. Your Astronaut Survival Manual suggests you eat 5.0 N of fruits and vegetables, 5.0 N of protein, and 2.0 N of fat everyday to stay healthy. Why is this diet a bad suggestion? 10. When you leave a planet, your rocket must consume fuel for thrust to escape the planet’s gravity. Arrange the planets from least amount of fuel needed to escape to the greatest amount of fuel needed to escape.
