What is the work done against the gravity when a body is moved horizontally along a frictionless surface?
force?
Liquids and gases exert a buoyant force on object placed in them?
Yes, liquid and gases exert a buoyant force on object because of the surface tension of the fluid.
When a body is placed on a surface it exert a force but the body does not move or fall why?
Because an equal and opposite force is being exerted on it.
Is force different in a frictionless floor?
yes it is
What does the coefficient of static friction represent?
In free space or on a frictionless surface, it takes no force to move something. Where there is friction, the ratio of (force necessary to start it moving horizontally)/(the object's weight) is the coefficient of static friction on the horizontal surface.
How do you escape from a frictionless room?
If you are in a frictionless room, you can't push off of anything to exert enough force to move away. However, if you have a bottle of compressed gas or liquid, the force of the escaping gas from the container will exert a reaction force to push you where you need to go. If you are near a wall, you can push off of that.
Which force is responsible for holding a car in a frictionless banked curve?
The Horizontal Component of the normal force.
When you sit in a chair it exert against you?
normal force
What is the work done against the gravity when a body is moved horizontally along a frictionless surface?
force?
What will happen if you apply a force on top of a disk kept on a frictionless surface?
The disc will slow down as a result of the friction applied by the force.
Which surface would exert the least frictional force on your feet as you walk?
Teflon, Ice or an oiled surface.
Liquids and gases exert a buoyant force on object placed in them?
Yes, liquid and gases exert a buoyant force on object because of the surface tension of the fluid.
Three blocks that are connected by massless strings are pulled along a frictionless surface by a horizontal force?
Well it's obviously not flying.
Is normal force supplied by the strength of the surface?
A normal force is a force perpendicular to something - for example, to a surface. This force can be supplied by just about anything; in many cases by gravity.A normal force is a force perpendicular to something - for example, to a surface.

Because an equal and opposite force is being exerted on it.
What of the surface is supplied by normal force?
static of the surface
