An object moves with a uniform velocity when pushing forces and frictional forces acting on the object are balanced and there is no net external force on it. This statement is given in my NCERT textbook. What do they mean?

Explanation:
In these lines, they have explained about Balanced forces.
See, they want to say that when any object moves with uniform velocity, the fictional forces act on the object and it gets balanced due to which the net force becomes zero.
But now, what is Uniform Velocity and Balanced force??
Before , we know about the uniform velocity, we should know that what is velocity???
Velocity :- It is total displacement covered upon total time taken.
Displacement means the shortest path covered.
Velocity is represented by V , displacement by d and time by t.
So, the formula becomes:-
V = d/t
________________________
QUE:- What is uniform velocity??
ANS:- When an object covers equal displacement in equal interval of time is called to be as uniform velocity.

QUE:- What is a balanced force?
ANS:- When there is equal force from the opposite {Both +ve and -ve} sides is called balanced force.

1. Velocity is a vector quantity.
2. Time is a scaler quantity.
3. Displacement is a vector quantity.
SCALER QUANTITY:- It has only magnitude but no direction.
It is always positive.
VECTOR QUANTITY:- It has both magnitude and direction.
It can be either positive or negative or zero.
