WebThe force exerted back by the spring is known as Hooke's law. \vec F_s= -k \vec x F s = −kx. Where F_s F s is the force exerted by the spring, x x is the displacement relative to the unstretched length of the spring, and k k is the spring constant. The spring force is called a restoring force because the force exerted by the spring is always ... WebF in the definition of potential energy is the force exerted by the force field, e.g., gravity, spring force, etc. The potential energy U is equal to the work you must do against that force to move an object from the U=0 …

Here, we chose to represent the displacement in an arbitrary direction by d →l, so as not to be restricted to any particular coordinate direction. WebWe can then take the gradient of our result (with respect to \( \vec{r} \)) to find the gravitational field \( \vec{g} \). ... the distance from infinitesmal mass \( dm \) to the point at which we're calculating the potential or force. … asa racing series
