The influencing factors of accelerating force were analyzed numerically, including relative position of coil and armature, current flow, coil size and armature size.

基于有限元方法，对弹丸受力的影响因素，如线圈与弹丸的相对位置、电流大小、线圈尺寸和弹丸尺寸等进行了数值分析。

But if I'm accelerating, the force exerted by the spring and therefore, the needle the weighing machine reads is m.

但是如果我在加速运动,那么弹簧的弹力,也就是称重机上指针的读数就是 m
