Name: Gravity Exploration Worksheet Part A: How much would you weigh on the moon and planets? The more mass a planet has compacted within its size, the stronger its gravitational constant. Earth has a gravitational constant of 9.8 N/kg. Planets that have more matter compressed within their volumes than Earth would have stronger gravitational constants at their surfaces. As a result, a person would weigh more on these planets than they do on Earth. On the moon a person would weigh less. Find your weight on the moon and each of the planets in the solar system. Weight on Earth (N)* Weight in lbs = ______ X Gravitational constant compared to Earth = Calculated Weight on… (N) Locati on You can convert you weight in pounds to newtons by multiplying pounds by 4.45N/lb. _______________ For instance, a person weighing 100lb on Earth would also weigh 445N on Earth X 0.17 = Moon X 0.38 = Mercur y X 0.86 = Venus X 0.38 = Mars X 2.87 = Jupiter X 1.32 = Saturn X 0.93 = Uranus X 1.23 = Neptun e Part B: How far could you jump on the moon and planets? Determine how far you can jump from a standing start on Earth. To do this, place a piece of tape on the floor as a starting line. Jump as far as you can, keeping both feet together. Have your partner mark where your feet hit the ground (not where you end up!). Measure this distance in centimeters and record in the table. Do this five times, then find the average.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
