A cooling fan sucks air through the mesh and blows it out the top of the locomotive — effectively the world's most powerful hair dryer. Using this method of deceleration saves a lot of wear from the mechanical brakes over time. Fully electric trains, as well as smaller vehicles like ...

The best way to reduce the initial force in a crash with a given amount of mass and speed is to slow down the deceleration. You've seen this effect for yourself if you've had to slam on yourbrakesfor any reason. The forces you experience in an emergency stop are much greater than wh...
Here we show how major rivers can efficiently connect to the deep-sea, by analysing the longest runout sediment flows (of any type) yet measured in action on Earth. These seafloor turbidity currents originated from the Congo River-mouth, with one flow travelling >1,130 km whilst acceleratin...
Deceleration The rate of change of velocity with respect to time, in a direction against current movement. It is still an acceleration, but against velocity, which means that whatever is being observed will be slowing down in at least one direction. Magnitude The size, power or value of somet...
How do I calculate the coefficient of friction when I'm only given the velocity and the distance, and the information that the deceleration is constant? A spring has a spring constant of 10 N/m. Find the magnitude of the force needed to compress the spring by 0.1 m. How do you calcula...
The association of smartness with selection for hyper-acceleration can create very narrow beliefs about what it means to be “good” at mathematics (Galanti et al., 2021). We use the term deceleration to describe a high-achieving student’s subsequent decision to leave the most rigorous course...
The Gaussian distribution describes a linearly increasing gain (constant acceleration) in information with magnitude, associated with a linearly increasing decline (constant deceleration) in relative probability with magnitude. The rate of the linearly increasing gain in information with magnitude is the ...
Physics tells us that energy can not be destroyed. So when your car slows down, the kinetic energy that was propelling it forward has to go somewhere. Most of it simply dissipates as heat and becomes useless. That energy, which could have been used to do work, is essentially wasted. Is...
Linear Velocity In physics, one of the first concepts we learn is how to find an object's velocity. When we're first starting out we're generally only concerned about objects going in a straight line. To this end, we learn how to find the average linear velocity of an object. ...
