surface tension
What else can I help you with?
What is the force that acts on the surface of a liquid?
surface tension
What force acts on the particles of the surface of a liquid?
its surface tension
What is the direction in which the surface tension acts when the liquid is at rest?
Surface tension acts perpendicular to the surface of the liquid, attempting to minimize the surface area and causing the liquid to form into droplets or exhibit a meniscus in a container. This force is due to the cohesive forces between the liquid molecules at the surface.
What is a force that acts on particles at a liquids surface?
Surface tension is the force that acts on particles at a liquid's surface. It is caused by the cohesive forces between the liquid molecules, which creates a barrier that resists the penetration of external objects or forces. This force is responsible for phenomena such as capillary action and the formation of droplets.
Is surface tension a contact or non-contact force?
Surface tension is a result of cohesive forces between liquid molecules at the surface, so it is a non-contact force that acts at the interface of the liquid with its surroundings.
What is the force that acts perpendicular to the surface of contact?
the normal force
What is the outward force from a surface?
The outward force from a surface is called normal force. It is the force exerted by a surface that is perpendicular to the surface and acts to support the weight of an object resting on it.
The force that acts on objects immersed in or floating on a liquid?
The force that acts on objects immersed in or floating on a liquid is called buoyant force. This force is exerted in the opposite direction of gravity and is a result of the pressure difference between the top and bottom of the object. Bouyant force is what causes objects to float in liquids.
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 type of force is directed parallel to the surface?
A force directed parallel to the surface is called a tangential force or a shear force. This type of force acts parallel to the surface of an object, causing it to slide or deform.
What force always acts in the opposite direction from gravity?
The normal force, exerted by a surface in contact with an object, always acts perpendicular to the surface and in the direction opposite to gravity to keep the object from falling through the surface.
What does normal force mean?
The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface and prevents objects from passing through the surface.
