In mechanics (physics), Hooke’s law is an approximation of the response of elastic (i.e., springlike) bodies. It states: the extension of a spring is in direct proportion with the load applied to it. For instance, the spring is pulled downwards with either no load, F p, or twice F p. Diagram of Hooke’s Law: The extension of the spring is ...
The simplest oscillations occur when the restoring force is directly proportional to displacement. This is called Hooke’s law force, or spring force: \ [F=-k x. \nonumber \] Here, \ (F\) is the restoring force, \ (x\) is the displacement from equilibrium or deformation, and \ (k\) is a constant related to the difficulty in deforming the system.
The force exerted back by the spring is known as Hooke's law. F → s = − k x →. Where F s is the force exerted by the spring, x is the displacement relative to the unstretched length of the spring, and k is the spring constant. The spring force is called a restoring force because the force exerted by the spring is always in the opposite ...
16 de feb. de 2015 · In terms of springs, this means understanding the laws of elasticity, torsion and force that come into play—which together are known as Hooke's Law. Hooke's Law is a principle of physics that ...
Explore Hooke's Law with interactive and fun simulations, stretching and compressing springs to observe effects.
Final length = 33 cm. Step 2: Write the relevant equation. F = ke. Step 3: Calculate the extension, e. e = final length – original length = 40 – 33 = 7 cm. Step 4: Convert any units. Since the spring constant is given in N/m, e must be in metres (m) 7 cm = 0.07 m. Step 5: Substitute the values into the Hooke's Law equation.
