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.

What type of contact force is perpendicular to the surface of contact?

Normal force is a type of contact force that is perpendicular to the surface of contact. It is the force that a surface exerts on an object placed on it, acting in a direction perpendicular to the surface.


What is the force that acts perpendicular to the surface of contact?

the normal force


Is Normal Force contact or non contact?

Normal force is a contact force that acts perpendicular to the surface of an object in contact with another surface. It arises from the electromagnetic interaction between atoms when two surfaces are pressed against each other.


How to find the contact force between two blocks with friction?

To find the contact force between two blocks with friction, you can use the formula: contact force normal force - frictional force. The normal force is the force exerted by one block on the other perpendicular to the contact surface, and the frictional force is the force resisting motion parallel to the contact surface. By calculating these forces, you can determine the contact force between the two blocks.


Which way does normal force act?

The normal force acts perpendicular to the surface that an object is in contact with. It is a reaction force that arises when two objects are in contact and prevents them from passing through each other.


Definition of normal force?

The normal force is the force exerted by a surface on an object in contact with it, perpendicular to the surface. It is equal in magnitude and opposite in direction to the force the object exerts on the surface due to Newton's third law.


What is the definition of a normal force?

The normal force is the perpendicular force exerted by a surface to support an object in contact with it. It acts in the direction perpendicular to the surface.


What is 2 contact forces?

Two examples of contact forces are friction and normal force. Friction occurs when two surfaces are in contact and resist an object's movement, while normal force is the force exerted by a surface to support an object resting on it.


What force counteracts a contact force to prevent objects from passing through surfaces?

The force that counteracts a contact force to prevent objects from passing through surfaces is called the normal force.


What is a force that results from physical contact between two objects called?

The force that results from physical contact between two objects is called contact force. This force can include friction, tension, normal force, and applied force.


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.


Kinds of contact force?

examples of contact forces are : friction, tension, normal force
