Weight is extremely useful in determining the frictional force on an object. Say we have a box on a level surface. The box has a weight of mg(mass times the gravitational constant). Since the box is still, and it is being supported by the ground, there is an equal and opposite force that is being exerted on the box by the ground, which pushes it up. This is known as the normal force. The force of Friction is defined as the greek letter mu(which is the coefficient of friction for the two materials against each other)times the normal force, which in this case is mg. Mu also varies depending on wether or not the box is moving in contact with the ground. A different coefficeint of friction is used instead of the one when the box is at rest. The frictional force on the object is always greater when the object is at rest than when it is sliding. Hope this helps!

Force that resits motion?
Force that resists motion is frictional force, viscous drag
What is the independent controlled and dependent variable of how mass effects the force of friction?
The independent variable is mass. The dependent variable is the frictional force.
What is the basic metric unit of weight?
Weight is the mutual gravitational force between the earth and any object on it.The basic unit of force is the Newton .
What is the name of the force that always acts against the direction of movement?
In geneal frictional force. If it rubs against a surface then it is known to be friction. If it drags the moving body then it is said to be viscous drag.
Are weight and mass he same thing?
No. The relationship is: weight = mass x gravity Mass causes both weight, and inertia. Weight is the force of attraction by gravity, and also depends on the gravitational field, not just on the mass. For more information, check the Wikipedia article "Mass versus weight".
What frictional force?
Frictional force is the force that opposes motion between two surfaces.
Who first stated the relationship between buoyant force and weight?
The relationship between buoyant force and weight was first stated by Archimedes.
Why does weight affect frictional force?
Given an object if contact with a surface, the limiting frictional force is directly proportional to the normal reaction to the weight of the object at its point of contact with the surface.
What is a spring balance use for?
to measure frictional force
What is the force that oppose motion between surface?
Frictional force
What is a static force?
A static force is a frictional force between two forces!
Which scientist first stated the relationship between buoyant force and weight of a displaced fluid?
Archimedes first stated the relationship between buoyant force and weight of a displaced fluid.
Does a frictional force between two objects increase with a force between them?
if you are talking about contact force, then you are correct. but if you are talking about some other external force,then the answer will be no. because frictional force only depends on the contact force between any two objects.
What is the relationship bewtween frictional force and sliding surface?
I can has friction? U mad?
How did the addition of more weight affect the friction?
When the weight increases the frictional force also increases:)
Is frictions force?
Frictional force is the force that opposes motion between two surfaces.
What is the relationship between the buoyant force and the weight of water displaced?
They are equal
