Hооke’s lаw is used tо define the restoring force which is used for mаteriаls that have elasticity, or a tendency to pull away from any applied force. A common device that adheres to Hooke’s law is a spring with a mass attached to it. Much like the frictional force, the restoring force points in the direction opposite the motion of the applied force and therefore opposite the motion of the block. If an applied force of 10N pulls a block attached to a spring horizontally 1cm and then holds it in place, how stiff if the spring when measured such that the block is at rest at 1cm?? That is, what is the stiffness constant as derived from Hooke’s law?? The spring is attached to a vertical wall at its other end, the end not attached to the block and is parallel to the ground on which the block sits; the spring is in the air and attached at the midpoint of the block and then is parallel all the way to attaching to the wall at a point above the ground equal to the midpoint of the block. Hint: the negative sign in front of the force means the force is pointing to the left, when the object is being pulled to the right, so you would not change the sign when doing a free body diagram; the sign is already assuming you are treating right to be positive, so the applied force will be opposite the restoring force.
