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,...
Work done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to themotionof the object, the work is considered to be negative, implying that energy is taken from the object. The units in wh...
Yes, work done by electric force can be negative. This occurs when the electric force and displacement are in opposite directions, resulting in a negative value for work. This means that energy is being taken away from the object by the electric force. What is the difference between work don...

In physics, the term work refers to the transference of energy that occurs when a force is applied to a body that is moving in such a way that the force has a component in the direction of the body's motion. Thus work is done on a weight that is being lifted, or on a spring tha...

Force is not constant across the distance that the spring is stretching because as the stretch distance increases, so does force. Using calculus, we can integrate the force equation with respect to distance to find work as follows: W = integral(F*dx) = integral(k*x*dx...
Example: The Work Required to Stretch or Compress a Spring Suppose it takes a force of 10 N (in the negative direction) to compress a spring 0.2 m from the equilibrium position. How much work is done to stretch the spring 0.5 m from the equilibrium position? Show Solution ...
You can announce the activity to the staff at the start of your designated spring cleaning day. The individual or team who recovers the most clues by day’s end wins a prize. To incentivize employees to keep these spaces clean, you may want to periodically re-hide clues that staff can ex...
