Question

The force that a solid surface exerts on any object in the normal
direction

Answer 1

Hii There!!!


⭕✔ A force that a solid surface exerts on any object in normal direction is called 'normal force'.



⭕✔ For example :- A body of mass 'm' kept on a flat surface. Here, normal force will be perpendicular to the surface of body kept in contact.

Answer 2

The force that a solid surface exerts on any object in the normal

direction is normal force.

• Normal force is defined as the force exerted by a surface on an object.
• For instance, consider a body of any mass resting on a flat surface.
• In this case, normal force will be perpendicular to the surface of the body with which it is in contact.
• The surface is perpendicular to the normal force.
• When an object is at rest, its net force is equal to zero; thus, the downward force (weight) must equal the upward force (normal force).
• Because weight acts downward, the result will be negative.
• When a book is placed on a table, for example, normal force prevents the book from falling through the table.
