The discussion focuses on understanding the effectiveness of Anti-lock Braking Systems (ABS) in vehicles. The user seeks guidance on how to demonstrate ABS effectiveness using numerical examples and relevant formulas. Key points include the function of ABS, which prevents wheel lock-up during braking, and the need for clarity on the physics principles involved. The conversation highlights a lack of familiarity with ABS compared to other safety systems like airbags and seatbelts. Overall, the user is looking for specific insights into the mechanics and calculations related to ABS.

Hi, I am in my first year of physics and am a bit lost. I need to know how to show the effectiveness of ABS using numerical examples and the formulas used.
I have no idea! we've had to do it for airbags, seatbelts, crumple zones and head restraints where I have a fair idea...I just don't know what I should be looking at with ABS.

ABS is a system to prevent the wheels from "locking up". What does that tell you?
Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky?
Thanks - rev
