If that force is not perpendicular to the surface, then there is a component
of the force that's parallel to the surface. That component would move fluid
around, until there were no longer any force parallel to the surface ... and the
whole force would again be perpendicular to the surface.
What else can I help you with?
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.
What is the upward force exerted on a body by that into which it is immersed?
When a body is immersed in water , due to pressure difference between upper surface and lower surface of the body an unbalanced upward force acts on a body . This unbalanced upward force is called Buoyancy force
How does water pressure work on someone swimming in a pool?
Pressure acts on any body of water, but you have to go really deep to notice the force.
Can a centripetal force ever do work on an object. explain?
Centripetal force refers to the force that acts on a body moving in a circular path. It does not do work on an object because it acts perpendicular to the motion of the body. The work done on a rotating object is zero.
What force acts by wall on body when a body hits at angle 60 and rebouds at angle 60?
When a body hits a wall at an angle of 60 degrees and rebounds at the same angle, the force acting on the body by the wall is the normal force. This force acts perpendicular to the surface of the wall and changes the momentum of the body in the direction normal to the wall. Additionally, there may be a frictional force acting parallel to the wall depending on the nature of the surface and the motion of the body. The overall interaction can be analyzed using the principles of conservation of momentum and the coefficients of restitution.
Can a force acting perpendicular on a body cancal a force which is acting horizontally on the same body?
Yes, a force acting perpendicular to a horizontal force on a body can cancel out the horizontal force if the two forces are equal in magnitude and opposite in direction. This is known as the equilibrium condition, where the net force acting on the body is zero.
Which force do not work on the body on which it acts?
frictional force
Why no work is done when force is perpendicular to the body?
How can a force be perpendicular to a point?! Surely you wanted to ask "Why no work is done when force is perpendicular to the direction of the displacement of the body?". This finds a simple answer in the definition of work: work done by a force F is defined asW := ∫ Fdr,where r is the position of the particle (that is, of the point of the body the force acts on), and hence dr is the direction of the displacement of the particle. From the definition, you immediatly see that if the angle between F and dris 90° (or, in general, (2n + 1)π/2, with n element of Z) the scalar product is Fdr = 0, and thus W = ∫0 = 0.
If an unbalanced force acts on a body what will happen?
If an unbalanced force acts on a body, it will cause the body to accelerate in the direction of the force. The acceleration will be directly proportional to the magnitude of the force and inversely proportional to the mass of the body, as described by Newton's second law of motion (F = ma).
How can you related of force with the change of momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How can you relate a force with the change of a momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How can you relate a force with the change of momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
