FRICTION
DEFINITION OF FICTION
Friction is a force that acts between two objects that touch as they move past each other.There are 3 ways friction is applied rolling,sliding,fluid.
SLIDING
Sliding friction is friction that acts on objects when they are sliding over a surface.Sliding friction can be useful. For example, you use sliding friction when you write with a pencil. The pencil lead slides easily over the paper, but there’s just enough friction between the pencil and paper to leave a mark.
ROLLING
Rolling friction is friction that acts on objects when they are rolling over a surface.That is why people use wheels to transport easier on the ground.
FLUID
Fluid friction is friction that acts on objects that are moving through a fluid. A fluid is a substance that can flow and take the shape of its container. Fluids include liquids and gases.An exaample is when you try to push the water.
