What are examples of physics in Apollo 13 and October Sky?

AI Thread Summary
The discussion highlights key physics concepts demonstrated in "Apollo 13" and "October Sky." In "Apollo 13," the slingshot maneuver around the moon illustrates gravitational assist, showcasing how spacecraft can gain speed and change trajectory using a planet's gravity. "October Sky" features projectile motion during the rocket launches, emphasizing the principles of trajectory and forces acting on the rockets. Additionally, the cave-in scene in "October Sky" can be analyzed through the concepts of structural integrity and forces acting on materials. These examples effectively illustrate the application of physics in real-world scenarios.

1. What are two examples of physics found in Apollo 13 or October Sky Physics







3. When they slingshot around the moon and in October Sky when they do the projectile and when the mine caves in. I need one more for Apollo 13..with explanation please

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
