The speed of an object does not require a direction to be considered, it simply has a value and unit, for example, 27 \(m\,s^{-1}\). Velocity is a vector quantity which requires a value, unit and ...

A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...

Abstract: This paper investigates the effects of target acceleration on estimating the velocity vector of a ground moving target from single-pass dual-channel synthetic aperture radar data. Although ...
