Question

What is restoring force in a spring balance?

Answer 1

Hello Mate,

Restoring force is the force that can be found in any oscillatory system to bring object in equilibrium position , for example in simple harmonic motion , or in spring motion . Restoring force is the force or torque that tries to restore a system back to equilibrium when its moved away from equilibrium..

Hope this helps you

Answer:

Balanced Forces

But what exactly is meant by the phrase unbalanced force? What is an unbalanced force? In pursuit of an answer, we will first consider a physics book at rest on a tabletop. There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.

Unbalanced Forces

Now consider a book sliding from left to right across a tabletop. Sometime in the prior history of the book, it may have been given a shove and set in motion from a rest position. Or perhaps it acquired its motion by sliding down an incline from an elevated position. Whatever the case, our focus is not upon the history of the book but rather upon the current situation of a book sliding to the right across a tabletop. The book is in motion and at the moment there is no one pushing it to the right.
