AI Thread Summary
When sitting at rest on the Moon, an astronaut experiences a weight force and a normal force, similar to sitting on Earth but with reduced gravity. The gravitational acceleration on the Moon is approximately one-sixth that of Earth due to its smaller mass and diameter. Although the astronaut is not moving, they still exert a downward force equal to their weight, which is the product of their mass and the Moon's gravitational acceleration. Therefore, a 50 kg astronaut would exert a downward force of about 83.3 N while sitting at rest. Understanding these forces helps clarify the dynamics of objects in different gravitational fields.

If you were sitting at rest on the moon, what forces would be present?

I know that there is a weight force, and maybe a normal force...
Thank you

Exactly the same forces as sitting on the Earth (neglecting air effects) - except with less gravity.
 
How much force does an 50 kg astronaut exert while sitting at rest?

I would assume 0 N since he is not moving but I'm not too certain...
 
He still has weight acting downwards.
Remember don't think about space and astronauts - he is a mass sitting on a planet, just one with a smaller 'g' there is nothing different about space.

'g' for the moon depends on both the smaller mass of the moon and it's smaller diameter - it's roughly 1/6 the value on earth.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
