In part (b), acceleration is not constant. During the 1-h interval, velocity is closer to 80 km/h than 40 km/h. Thus, the average velocity is greater than in part (a). Figure 3.18 (a) Velocity-versus-time graph with constant acceleration showing the initial and final velocities v0a...

Model experiments relating to thermals with increasing buoyancy It has been found possible to achieve experimentally two simple kinds of motion, namely, constant velocity or constant upward acceleration. These elements spread linearly with height in agreement with the predictions of a dimensional theory,...

Orbital motion of spacecraft under the action of constant-thrust acceleration in the direction perpendicular to the velocity is studied. A spacecraft starting in an initial circular orbit obtains a minimum (perigee) radius along an inbound trajectory. If the thrust is maintained, the spacecraft re...
6) motion with uniform acceleration 等加速度运动补充资料:极限星等 用附有辐射探测器的望远镜所能观测到最暗的恒星星等。它主要由下列三个因素决定。①望远镜系统在单位像面上能收集到的辐射流量,这和望远镜的口径D、焦距f 以及大气吸收有关。②辐射探测器将这些辐射流转换成可测量的信号,其大小和探测器的量子...
