As per the name, you can guess the meaning of this force.
A normal force is a force which is acting in the perpendicular direction.
In physics, the definition of normal force can be stated as:
“A force which is normal (perpendicular) to the surface of an object is known as a Normal Force“
To understand the above statement properly,
Let’s take some Real Life examples. (So you’ll get an exact idea)
Normal Force Examples in our Daily Life
Here’s a list of Daily Life examples of normal force:
- Girl standing on a flat surface
- Book placed on a table
- Banana crate placed on a floor
- Television resting on a table
- Flower pot placed on a table
- And more…
Let’s understand each one of these examples with pictures.
#1 Girl standing on a flat surface
When a girl is standing on a flat surface, one perpendicular force acts on a girl.
As this force acts perpendicular to a girl, it is known as a Normal Force.
#2 Book placed on a table
When a book is placed on a table, one perpendicular force acts on a book.
As this force acts perpendicular to the surface of a book, it is known as a Normal Force.
#3 Banana crate placed on a floor
When a banana crate is placed on a floor, one perpendicular force acts on a banana crate.
As this force acts perpendicular to the surface of a banana crate, it is known as a Normal Force.
#4 Television resting on a table
When a television is resting on a table, one perpendicular force acts on a television.
As this force acts perpendicular to the surface of a television, it is known as a Normal Force.
#5 Flower pot placed on a table
When a flower pot is placed on a table, one perpendicular force acts on a flower pot.
As this force acts perpendicular to the surface of a flower pot, it is known as a Normal Force.

There are so many other examples of normal force that we are experiencing in our daily life.
Summary
From the above examples, one thing is understood.
If a force is acting in the perpendicular direction, then a force is said to be a normal force.
That’s how you can easily remember the definition of normal force:
“A force which is normal (perpendicular) to the surface of an object is known as a Normal Force“
