An object's average acceleration over a period of time is its change in velocity ( \ Delta \ mathbf { v } ) divided by the duration of the period ( \ Delta t ).

A 1 km long mass driver made of superconducting coils can accelerate a 20 kg vehicle to 10.5 km / s at a conversion efficiency of 80 %, and average acceleration of 5, 600 g.

Are you sure that this is the correct equation, Dragons flight ? 6.82 days would be an average acceleration of 0.00221 m / s 2, which is "'smaller "'than the initial acceleration of 0.00270 m / s 2!

The average acceleration ( due to many photon absorption events over time ) of an atom with mass, M, a cycling transition with frequency, \ omega = ck + \ delta, and saturation intensity of the laser ) is

However, in the second case you're calculating the average acceleration, which doesn't seem of much use to me, say, when calculating a car trip, since the acceleration is so uneven ( sometimes positive, negative when you brake, sometimes zero ).

Average acceleration from zero to 60 miles ( 96 kms ) an hour has been cut by nearly two seconds while passenger vehicles now weigh on average 500 pounds ( 227 kilos ) more than they did in the mid-1980s, according to EPA.

For example, if you accelerate at 1 g to the half-way point of your journey to the Moon, then turn around and decelerate at 1 g for the second half of the journey, does that mean your average acceleration is 1 g or 0 g?

The best average acceleration in a truck with a Caterpillar C15 engine is achieved by going all the way up to 1950RPM, then shifting to a gear that will put the engine at 1500RPM, so that the truck is receiving as close as possible to maximum power throughout the entire time it is accelerating.
19.
The reason for the trouble is that we are told to evaluate the average acceleration on a precise time interval, so if there's a change at one end or the other there's no way for it to be so fast that we don't have to worry about its precise duration and shape .-- Tardis 19 : 33, 21 September 2007 ( UTC)

This slope therefore defines the average acceleration over the interval, and reducing the interval infinitesimally gives \ begin { matrix } \ frac { dv } { dt } \ end { matrix }, the instantaneous acceleration at time t, or the derivative of the velocity with respect to time ( or the second derivative of the position with respect to time ).
