What else can I help you with?
What energy changes take place when you use a boat?
Usually the water force friction takes place of the boat it pushes the gravitational force and the friction force takes place
Is static friction and limiting friction the same?
Limiting friction is the case of static friction where an object is right on the edge of moving, any more force applied to the object will cause it to move. Limiting friction is the largest value that the static friction can take
Does friction have force?
Yes,friction have force because if there is no force then friction cannot take place. Force is a thing 1.from which we can move from rest 2.from which we can change the state of motion 3.from which we can change the shape of an object 4.from which we can change the direction of motion of an object 5from which we can the speed of an object
How do you find the force of contact between two blocks?
It depends how they are in contact. If one is simply resting on top of the other you need to take into account, the friction coefficient which can be calculated from the Reynolds number of the particular material; and the mass of the object as the heaver it is the more friction will come into play.
Does it take the same amount of force to start something as it does to keep it moving?
No. It takes a force to put something in motion, and it takes force to stop it. To keep it moving requires zero force. If there is no opposing friction force, it will continue moving forever. If you can significantly reduce the friction, a small force can keep an object moving - just enough to counteract the force of friction.No. It takes a force to put something in motion, and it takes force to stop it.

Why do you need to do walk?
If there was no friction, your foot would simply slide back as you tried to take steps, and you would go nowhere. In order for something to move, it has to have a force moving it. That force has to have leverage, or friction. For the force pushing a person forward, there is an equal force pushing backward on the ground or floor. You can observe this by placing round pencils under a board, stand on it, and try to step off in the perpendicular direction : the board will roll backward as you step forward.
Does it take more force to pull a large item or more force to pull a small item?
The larger in weight would take more force Also, the larger if they are the same weight would take more force, because of friction and air resistance
It usually take more force to start an object sliding than it does to keep an object sliding because static friction is usually than sliding friction?
usually greater than the sliding friction
How much force will it take to pull 200 pounds?
To pull an object weighing 200 pounds, the force required will depend on several factors, including friction and the angle of the pull. In a frictionless environment, you would need to exert a force equal to 200 pounds to overcome gravity and initiate movement. However, if there is friction, you would need to exert additional force to overcome that resistance as well. Therefore, the total force required could be greater than 200 pounds, depending on the specific circumstances.
How does friction stop something from moving?
There are normally four forces acting on a body. They are friction force, applied force, weight and gravity. Friction is an opposing force that creates resistance to a body causing it to slow down. e.g If we have a car accelerating 1.55ms-2 and it weighs about 1400kg with its passenger and fuel. The applied force would be 2100N. The air resistance or drag force and the friction of the tries between the surface of the road has generated about 19500N. If we take away the friction force from the applied force, 2100N - 19500N = 600N of applied force to keep the car going but remember that this friction force will gradually slow down the car.
Is friction and static the same?
Limiting friction is the case of static friction where an object is right on the edge of moving, any more force applied to the object will cause it to move. Limiting friction is the largest value that the static friction can take
Does height affect friction?
Actually the study of friction is complicated and the usual statement that, say, the kinetic frictional force is proportional to the weight of the object is more a rule of thumb than a law of physics. For one thing, friction depends on the exact nature of the surfaces in contact, what materials the surfaces are made of, what is the microscopic texture of the materials, etc. If you are considering two solid surfaces, one way of thinking about the friction between them is that on the microscopic level, the surfaces are actually very rough, with many sharp peaks and valleys. When you put two materials together with little force between them, they really only touch at the tips. So if you were to pull sideways, it would take little force to move the materials across each other. But if the force between the blocks increases, then the tips penetrate into the valleys, they bend to allow a larger area of surface to come into contact, they even can make microscopic welds between the materials. In this case, it takes a much bigger sideways force to slide the materials across each other. Hence, the increase in friction.
