Because like a cannon when the cannon ball comes out the cannon goes forward that's reaction force. Normal force is where the force does not use a ton of force so you don't see it react.

A normal force is also known as a reaction force, and this is true because of Newton's third law of motion. And it should be a contact force, because it is only exerted perpendicularly on an object by another when that object is in contact with a plane

What type of contact force is perpendicular to the surface of contact?
Normal force is the component perpendicular to the surface in mechanics. It prevents an object from penetrating the surface with the contact force exerted.
What kind of force is friction?
Frictional force is a contact force which opposes the relative motion. It is directly proportional to the normal reaction between the 2 surfaces.
Does the frictional force depends on the contact area?
The contact area hardly affects the frictional force. The frictional force depends on the normal force, and the coefficient of friction, which is a property you have to look up (or measure) for every pair of materials.
How does the coefficient of friction depend upon the normal force between the surfaces in contact?
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
Is elastic force a contact force or a non- contact force?
A spring force is a contact force not a non-contact force.
What is the force that acts perpendicular to the surface of contact?
the normal force
Definition of normal force?
Normal Force- this is the support force exerted on an object in contact with another stable object.
What type of contact force is perpendicular to the surface of contact?
Normal force is the component perpendicular to the surface in mechanics. It prevents an object from penetrating the surface with the contact force exerted.
Kinds of contact force?
examples of contact forces are : friction, tension, normal force
What kind of force is friction?
Frictional force is a contact force which opposes the relative motion. It is directly proportional to the normal reaction between the 2 surfaces.
3 contact forces?
The three contact forces is push or pull or friction & the non contact force is gravity & magnitism.
Does the frictional force depends on the contact area?
The contact area hardly affects the frictional force. The frictional force depends on the normal force, and the coefficient of friction, which is a property you have to look up (or measure) for every pair of materials.
How does the coefficient of friction depend upon the normal force between the surfaces in contact?

Is elastic force a contact force or a non- contact force?
A spring force is a contact force not a non-contact force.
What are three contact forces that can change the motion of a ball?
force,motion,and friction
Why does weight affect frictional force?
Given an object if contact with a surface, the limiting frictional force is directly proportional to the normal reaction to the weight of the object at its point of contact with the surface.
What are the two factors that affect the friction force between two surfaces?
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
