一个弹簧从它的平衡位置被压缩0.31米，然后被释放并返回到其平衡位置，在此过程中，弹簧将弹丸推动并加速。弹簧的常数为75 N/m，弹簧对弹丸做多少功？解：弹簧对弹丸施加的力F（x）=kx，X=0.31米，弹簧做功为W=∫[0, 0.31]F（x）dx=0.5kX²=0.5·75·0.31²=0.0360375（...
Spring force(弹簧力)是指当物体被压缩或拉伸时,由弹簧产生的恢复力。弹簧是一种具有弹性的物体,它可以在受力作用下发生形变,并且在去除外力后恢复到原来的形状。 弹簧力是弹簧对物体施加的力,其大小和方向与弹簧形变的程度有关。根据胡克定律,弹簧力与物体位移之间的关系是线性的,即F = -kx。其中,F是弹簧力,...
When you have work done by constant forces, you can always calculate them by using fdcosθ. But when you have variable forces like the spring force here, then we're going to have to use the average of the force instead. So we're going to use fdcosθ, but we're going to have to...

spring可以取什么团队名 回复 共3条回复我来回复 worktile 团队名的选择应该根据团队的特点、目标和团队成员之间的共同喜好来确定。对于一个与spring相关的团队,以下是一些可能的团队名字: "Spring Force" 春天的力量 "Eternal Bloom" 永恒的绽放 "Green Awakening" 绿色觉醒...
Learn about the concept of variable force, the work done by a variable force and the graphical interpretation force-displacement curve by visiting BYJU'S.
To solve for the work done, we will need to evaluate this equation at 0.6m and 0.3m and find the difference between those two points. Because the force that is stretching the spring must be acting in the direction of the stretch, we know that the work will be posi...
