AI Thread Summary
To find the gravitational force acting on an object at an angle, the simplest formula is a = g sin(x), where g is the acceleration due to gravity (approximately 9.8 m/s²) and x is the angle. The discussion also touches on calculating gravity's effect on a 100 kg mass, emphasizing that gravity remains constant at 9.8 m/s² when standing still on Earth. Additional scenarios, such as jumping on a trampoline or being in a lift or roller coaster, highlight that gravity's force can vary based on motion and acceleration. Understanding these concepts is crucial for Grade 11 physics students. Mastery of these formulas aids in grasping the principles of gravity in different contexts.

Gravity Formulas urgent

I have to find the gravity acting upon an object, given an ANGLE. What would be the simplest formulae to use, I forgot my wrk sheet at school. I just need the simplest formulae, i found some but these are hard for me, we didn't use these (I'm in grade 11);

wait i found this would it work: a = (g) sinx

Perhaps you have not written the question very well, but answer the following:

You have a mass of 100kg. What is the force of gravity acting on you [magnitude and direction] when you are standing still, on the Earth where g = 9.8?

What is the force of gravity acting on you while you jump on a trampoline?

What is the force of gravity on acting you when you are in a lift?

What is the force of gravity on acting you when you are riding a roller coaster?
 

Thread 'Errors and significant figures'

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
