Well, let's say we have a siperin, right, and it is attached to a mass m.
00:08
And let's say the sipping constant of this siperin is k.
00:13
Then restoring force is given by f is equal to minus k times x.
00:22
Here, f is directly proportional to x.
00:26
Well, x is the displacement of the mass.
00:28
And f and x so restoring force and x are always in the opposite direction so here x is x can also be called change in length so x is change in length right okay well if we apply a force f to the sipering it will extend to the distance x, let's say if you apply a force, f, then this zippling extends to a certain distance, let's say x.
01:13
Now when the length is cut in half, and again, the same force is applied to the sipering, it will extend by only x divided by two...
