Re: Do you feel safe on Disney attractions?
It's not like Disney is free of ever having a coaster derail. California has some rather strict regulations for fixed amusements and Disney coming up short played a role in those regulations being instituted.

Originally posted by Jj94 View PostYes, whoever, you are absolutely correct! ...However, when we consider the effects of air resistance in a real world environment, mass does affect acceleration. Here's why:
Warning: Physics below!
Example 1: Free-Falling Object
If we were to look at an object free-falling, only 2 forces act on the object: (1) gravity downwards and (2) drag upwards. Using Newton's Second Law of Motion, we get the following:
[ATTACH=CONFIG]37198[/ATTACH]
The equation for the force due to drag is:
[ATTACH=CONFIG]37199[/ATTACH]
where, rho is density, v is velocity, C is the drag coefficient, and A is the cross sectional area.
The equation for the force due to gravity is:
[ATTACH=CONFIG]37200[/ATTACH]
where m is the mass of the object and g is the acceleration due to gravity.
Therefore, when we plug them into our original equation, we get:
[ATTACH=CONFIG]37201[/ATTACH]
When we divide both sides of the equation by m, we get:
[ATTACH=CONFIG]37202[/ATTACH]
So, an object with more mass would accelerate faster than an object with less mass. We can also see that by setting a = 0, we can derive the equation for terminal velocity:
[ATTACH=CONFIG]37203[/ATTACH]
where an object with greater mass would have a higher terminal velocity than an object with less mass.
Example 2: Object Going Down A Slope
What if we were to consider an object going down a slope? There will now be 2 additional forces added to the mix! The relevant forces would be: (1) gravity downwards, (2) a force from the slope pushing up on the object (force normal), (3) drag force, and (4) friction.
I'm going to skip some steps here but the process is still the same as before when we apply Newton's Second Law of Motion.
In the end, we get the following equation for acceleration:
[ATTACH=CONFIG]37204[/ATTACH]
where mu = friction coefficient, theta = angle of the slope, and the rest I've already described above somewhere.
Again, we see that the mass of the object still matters in the determination of the acceleration.
If we really wanted to get technical, we could talk about the internal friction of the bearings, buoyancy of the log, and other forces, but even at the simplest levels, we can see the role that mass has in determining the acceleration...
TL;DR: In a vacuum, mass does not matter when determining the acceleration but in the real world, it does.

Re: Do you feel safe on Disney attractions?
The only thing that makes me feel unsafe is that you can take bags, cameras and coins on the screamin. In Australia you can't even have anything in your pockets in any coaster

considering the huge amount of people who have ridden each ride, the number of fatalities at Disneyland is very small.
I've never felt truly "unsafe" on a ride, though. The only ones that REALLY get to me are rides I am terrified of, like roller coasters (Screamin'). That's really the only one I can genuinely say I hate to go on despite having gone on it twice already.

Re: Do you feel safe on Disney attractions?
The only time I ever felt unsafe on a ride at DLR was (as others have mentioned) because of me, not the ride. A while back I had a minor concussion. I had been symptom free for I think at least a week before I went to Disneyland. I figured I'd be fine. Mostly, I was. But at a certain point, I think I was on Screamin' and realized it was probably a very bad idea to go back to the park quite so soon. But again, the feeling wasn't that the ride itself was unsafe, just that I'd made an incredibly poor decision to ride it at the time and was worried I was damaging my health. Scary experience.

Re: Do you feel safe on Disney attractions?
Yup. Never a doubt about ride safety at Disneyland. Those rides get checked far more often than your own car does for safety. You have a higher chance of falling down your own stairs than getting hurt on a theme park attraction.
But they make big splashy news stories so they get reported when they happen.

Re: Do you feel safe on Disney attractions?
I feel perfectly safe. The only ride I felt less than 'perfectly' safe was Goofy's Sky School. But that's due to me, not Disney.

Originally posted by laferney Road kid View PostI never feel safe on Goofy flight school. The fear is compounded by my 6'5 body not fitting into the attraction vehicle. Every time we whip around the curves on the top deck the fear surfaces, "This is the time I am going to go flying off." It just takes one ride to feel that discomfort all over again. But now that I know that Disney imagneers have created a runaway flying car that will land wheels first on the the Gazebo, restrooms, and trees from Paradise Garden Grill combined with the exit covering at Goofy's would help cushion the fall of any vehicle that derailed near the top edge.
Not in jest, my retirement plans were to travel Greyhound to Disneyland. Those plans are now scary and not going to do that!!!!!!

Your safety is much more questionable on the 5, than anywhere inside the park. LOL!

I feel safer at Disneyland than I do at the local fair, although I go on that one too.

Re: Do you feel safe on Disney attractions?
I get scared on lift hills of any coaster, Disney's included (Thunder Mountain and California Screamin' in particular come to mind). But that's more of a personal phobia than a legitimate concern for the safety of the ride. Also, swing rides like the Silly Symphony Swings freak me out. Have always been afraid of the chain breaking somehow and the swing flying off into the water or over the cement (again, a quirky personal phobia). However, I feel safer on Silly Symphony Swings than any equivalent swing ride at other parks for some reason and do enjoy them a lot (unlike, say, the swings at the Santa Cruz Beach Boardwalk which only manage to terrify me).
This conversation reminds me of all the things I used to be scared of at Disneyland as a little kid--thinking the cannons on POTC were real and that they might hit the boats, being afraid of plunging into lava on IJA, refusing to take the driver's seat on Toad because I was convinced that you actually controlled the vehicle and didn't want to crash into the train (dido for Indy). Those were the days that I legitimately feared for my safety.
