1. Metres per second squared.
A measure of acceleration Acceleration, in physics, is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law.[1] The SI unit for acceleration is metre per second squared (m s−2). Accelerations are vector quantities (they have magnitude and direction) and add according to the parallelogram law.[2][3] As a vector, the calculated net force is equal to the product of the object's mass (a scalar quantity) and its acceleration. For example, when a car starts from a standstill (zero relative velocity) and travels in a straight line at increasing speeds, it is accelerating in the direction of travel. If the car turns, an acceleration occurs toward the new direction. In this example, we can call the forward acceleration of the car a "linear acceleration", which passengers in the car might experience as a force pushing them back into their seats. When changing direction, we might call this "non-linear acceleration", which passengers might experience as a sideways force. If the speed of the car decreases, this is an acceleration in the opposite direction from the direction of the vehicle, sometimes called deceleration.[4] Passengers may experience deceleration as a force lifting them forwards. Mathematically, there is no separate formula for deceleration: both are changes in velocity. Each of these accelerations (linear, non-linear, deceleration) might be felt by passengers until their velocity (speed and direction) matches that of the car. Simples ! |

The size of the universe !
My head is having difficulty get that in perspective There's a great channel on you tube: 'David Butler' He does a series of 18 videos 'How Far away is it' starting off on earth, going to the edge of the visible universe. . https://www.youtube.com/watch?v=bcn0ycIHKog ( This is 3/18 as the first 2 are just openers ) Also Does How Small is it How fast is it. All of high BBCesque quality. |

The OP is a bit like Fr Dougal struggling with getting his head around perspective. I mean, how is it possible to live in three dimensions without being able to get one's head around the concept of acceleration?

Why they call it Correct Score.
What's wrong with 'Score'. Do they need to differentiate it from the Wrong Score market, whereby all bets are winners apart from the one which is right. (Which is wrong) You don't have 'Correct' in any other market name FFS! |

(Metres per second squared is just a shorthand way of saying something is accelerating at a rate of so many metres per second per second. For instance, the acceleration due to gravity is 9.8 metres per second per second - or 9.8 m s−2. So, if you jumped, say, from your bedroom window to escape Bruce Forsyth, and hit the ground 2 seconds later, your speed when you hit the ground would be 19.6 metres per second - 2 times 9.8.) |

Why we all have strong memories of certain seconds in our life that really were not important at the time but they keep popping up in the mind from time to time.Anyone know why an unimportant event can be remembered so clearly .There must be some reason for it.
