The definition of uniform variable speed linear motion is the same acceleration, that is to say, as long as the speed change / time change is the same? Look at it The definition of uniform variable speed linear motion is the same acceleration, that is to say, as long as the speed change / time change is the same? Don't stress that the speed change must be the same in the same time, as long as the ratio is the same? That is, the speed change in two seconds is four meters per second, and the speed change in four seconds is eight meters per second. So the acceleration is the same, so is he still moving in a straight line with constant speed?

No, it is true that the acceleration can be obtained by △ V / △ T, but the factors determining the acceleration are the external force and the mass. Therefore, it can be said that as long as the magnitude and direction of the force are the same and the mass are the same, the acceleration must be the same; but it cannot be said that as long as the ratio of the velocity change to the time change is the same, the acceleration will be the same
