Physics Homework. I'm in year nine. I'm an idiot. Please help. Task: Force Diagram?

Question

Please don't give me annoying unwanted answers.

Here's the question, just point me in the right direction:

"Our interplanetary scientist, Cefor, has sent some electronic cards from her visits to places in our solar system. You have asked her to tell you her weight and mass at each place.

Moon:
Mass - 10 kg
Weight - 11.6N

Venus:
Mass - 10kg
Weight - 90N

Mercury
Mass - 10kg
Weight - 40N

When Cefor left Earth, she had a mass of 10kg and a weight of 100N.

Task: Draw a force diagram for Cefor standing still on Earth and on the three other places. Use the level ladder instructions to help explain your ideas.

Key words: acceleration, force, gravity, killograms, mass, Newtons, reaction"

I'll be really grateful if you help me!

Thanks x x

Answer 1

Weight is a force, properly measured in Newtons (N).
Force has a direction, and the force of weight is always in the down direction. Weight would be an arrow pointing down in the diagram. There would have to be a equal and opposite force from the ground holding him up, so he didn't sink into the ground.

Mass is not a force. Mass is measured in kilograms (kg).

Force = mass times acceleration.

For weight the acceleration is that of gravity. It is about 10 meters per second squared on Earth and only about 1.6 on the Moon.

10kg * 10 m/s^2 = 100 N (Earth)
10kg * 1.6 m/s^2 = 16 N (Moon)
(I see an error in your question, since it seems you are assuming 1.16 for acceleration of gravity on the Moon.)

I don't know what the level ladder instructions are so I can't help you there.
