Rolling Friction is caused by a rolling object such as a wheel when rolling over a surface. Sliding friction is cause by the brishing of an object along with the medium that it is sliding on. This can be visualize by sliding down a hill with a sled in the snow. Fluid friction, by fluid we are alluding to any substance that flows. Therefore air and water for both examples are fluid. When swimming or when is a bird is flying fluid friction is being acted upon them Good luck Stephane E. Fouche

What are some simple examples of sliding friction?
sliding in a slide
What are some simple examples of static friction?
Some simple effects of static friction are car tires when they are not sliding. While a car is rolling, the point on the wheels that is touching the ground is moving with zero velocity. Thus, contrary to popular belief, this is an example of static friction, not kinetic. Another is a box sitting on an incline, and yet another is you sitting in a chair at this computer. Each is a case of friction in which two objects contact each other and do not move.
How does rolling friction compare to sliding friction?
Rolling Friction is caused primarily by the interference of small indentations formed as one surface rolls over another. This is the idea behind the frictional forces involved with wheels, cylinders, and spheres. In the ideal case of the wheel, we must first look at the forces acting on the wheel. In pure rolling motion, friction is required to stop, start and change the motion of a wheel. Static Friction is a force which resists the lateral movement of two objects which are touching each other. A simple example of static friction might be a wooden block sitting on a ramp. Unless sufficient force is exerted, the block will not slide down the ramp, because static friction holds its place and resists sliding. When objects have a high coefficient of friction, it means that a lot of force will be required to break through the force of static friction and create movement, while low coefficient means that less force will need to be exerted.
What would happen if you walked on ice?
Ultimatley, the friction would resist to stop you from sliding, so you'd slip and fall. Kind of simple......
Is rolling eyes up a simple motor tic?
Rolling eyes up is a simple motor tic
Why so helpful to reduce friction on simple machines?
Friction force oppose motion between two bodies that are in contact. This force is important in machines and pulley systems in that it enables the gears to have grip and there is no unnecessary sliding.
Where is inertia based on?
Inertia is the tendency to not want to change, or in simple words, to keep doing what you're already doing. That means when a ball is rolling down the hill, it has inertia; it does not want to stop rolling. However, the ball will eventually stop because of friction or an object acting as an obstacle.
Is there a formula for friction?
simple one is: max friction = coefficient of static friction*normal force
What is the force that opposes motion between two objects?
Kinetic FrictionA more simple definition is "a force that oppsoes motion". i actually dont know the real answer so i wrote this cause it looks smart :D... sorry for wasting your time!!!!
How do simple machines help things move?
By reducing friction [rolling instead of dragging across a surface]By decreasing the amount of force needed to perform an action (at the cost of reducing the amount of action) [levers, inclined plane]
What is the definition of a simple motor?
definition of a motor
What describes the relationship between friction and IMA for a simple machine?
