What forces cause normal expiration?
During normal expiration, the primary force responsible is the relaxation of the diaphragm and external intercostal muscles, leading to a decrease in thoracic volume. This increase in pressure within the lungs causes air to be pushed out. Additionally, elastic recoil of the lungs and chest wall helps to facilitate expiration by returning them to their resting position after inhalation.
What does the friction force vs normal force graph reveal about the relationship between friction force and normal force?
The friction force vs normal force graph shows that there is a direct relationship between the friction force and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is proportional to the normal force.
What does the friction vs normal force graph reveal about the relationship between friction and the normal force?
The friction vs normal force graph shows that there is a direct relationship between friction and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is dependent on the normal force acting on an object.
What is Normal expiration is brought on by?
Normal expiration is brought on by the relaxation of the diaphragm and external intercostal muscles, causing the thoracic cavity to decrease in volume, which increases the pressure in the lungs. This increased pressure pushes air out of the lungs.
Why is the support force on an object called the normal force?
The support force on an object is called the normal force because it is perpendicular (normal) to the surface on which the object rests. It acts in the opposite direction to the force of gravity to keep the object in equilibrium.

The force responsible for normal expiration is supplied?
Nothing. The relaxed state of the chest is fully exhaled. Breathing out, expiring, is normally accomplished by relaxing the diaphragm and the muscles of the ribs. No force is used. It is possible to exhale forcefully, but the question did not ask that.
Which force is responsible for holding a car in a frictionless banked curve?
The Horizontal Component of the normal force.

What is the role of the normal force at the top of a loop in a roller coaster?
The normal force at the top of a loop in a roller coaster is responsible for providing the necessary centripetal force to keep the riders moving in a circular path without falling off the track. It acts perpendicular to the surface of the track to counteract the force of gravity and ensure the riders stay safely in their seats.
What the normal force is for an object on a flat surface?
The normal force for an object on a flat surface is equal in magnitude and opposite in direction to the force of gravity acting on the object. It is responsible for balancing out the gravitational force to keep the object stationary or in equilibrium on the surface.
What is the equation for calculating the normal force acting on an object?
The equation for calculating the normal force acting on an object is: Normal force mass x gravity.
Can a frictionless surface exert normal force?
No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.
