Explanation:Balanced and Unbalanced Forces

First Law

Inertia and Mass

State of Motion

Balanced vs. Unbalanced Forces

Newton's first law of motion has been frequently stated throughout this lesson.

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

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.

 

Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium. There is no unbalanced force acting upon the book and thus the book maintains its state of motion. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not accelerate. (Note: diagrams such as the one above are known as free-body diagrams and will be discussed in detail in Lesson 2.)

Consider another example involving balanced forces - a person standing on the floor. There are two forces acting upon the person. The force of gravity exerts a downward force. The floor exerts an upward force.thankuou mark my answer brainiest please.

Answer 2

In this question, we are asked to discuss about balanced and unbalanced forces.

• Forces acting on a balanced object do not change it from its uniform motion or condition of rest.
• The resultant of two opposing forces operating on an object and bringing it in motion. Unbalanced forces are these opposing forces.
• When an object is in equilibrium, that is, it is not moving with changing speed, the net force acting on it is balanced.
• For instance, the weight of an apple hanging from a tree is balanced by the force of the branch pulling on the apple.
• When an object is moving at different speeds, the net force on it is uneven.
• For instance, when an apple falls from a tree, it experiences an imbalanced force equal to its weight.
• Unbalanced forces produce a resultant force acting on the object in a particular direction which tends the object to accelerate in that particular direction.
