0:00 Hello.

00:01 So according to hooke's law, the force on a spring is given by f is equal to minus kx where k is the spring constant and x is the extension of the spring from its position of equilibrium.

00:27 Okay.

00:28 This negative sign shows that the visualized spring force is a restoring force and acts in the opposite.

00:36 Direction.

00:37 Okay.

00:38 Now what happens if the spring constant is increased for the same force? we can see here that the force is directly proportional to x.

00:48 Okay, for the extension of the spring from its equilibrium position.

00:53 The constant of the spring, k, is the symbolic of how rigid the spring is.

01:00 Okay, the greater the spring constant, the stiffer the spring is.

01:06 So, for different elastic artifacts, the spring constant does not reflect the same value.

01:13 The extension is directly proportional to the applied force for a given spring and other elastic artifacts.

01:21 Okay.

01:22 Suppose we have a spring having a spring constant k.

01:26 Okay, now we are applying a force f on the spring, and the.

01:30 Extension produced is equal to x.

01:33 Okay, then we can write f is equal to minus kx.

01:37 Now we are considering another scenario where we'll be applying the same force, but the spring constant changes.

01:46 The spring constant is double the spring constant of the first spring...
