What is Unbalanced Force
Examples of Unbalanced Force
Unbalanced Force Equation
What happens when an unbalanced force acts on an object? Here are some facts and characteristics of the unbalanced force. When an unbalanced force acts on an object, the following can happen:
Causes change in an object’s motion: A stationary object moves with acceleration. A moving object changes its direction or speed or comes to a stop. The motion obeys Newton’s law.
The applied forces are added when they are in the same direction and subtracted when they are opposite.The sum of all forces acting on the object along a line is never equal to zero.

Unbalanced Force Formula: F1 – F2 ≠ 0 For example, a book of mass m is lying on a table. An externally applied force FA acts on it. It overcomes the friction FK and moves with an acceleration a. According to Newton’s second law, the force experienced by the book is given by ma = FA – FK As can be seen, the result of unbalanced forces is to accelerate the object.
