Small Introduction to the Friction Force
Friction force is a force that is opposite to the pushing force and to the motion of an object when it is in contact with another object or material.
The friction is caused by the material that the is in contact with (water, air, the table, sand). It (the friction force) increases in the same way of the pushing force until the friction force reaches the highest point (it depends on the object and the surface it is in contact with). When that happens the object start moving.
When the object is not moving (and there’s a pushing force) it’s because the Friction FOrce is still increasing and it’s called Static friction. When the object is moving there’s still friction force but it’s minor and it’s called Kinetic Friction.

What is autism?
Autism is a developmental disorder that is characterized by impaired development in communication, social interaction, and behavior. Autism afflicts one out of every 100 to 166 children and it affects the lives of many children and their families (DiCicco-Bloom et al, 2006). It tends to affect about five boys to every one girl (First, 2008). Autism is classified as a pervasive developmental disorder (PDD), a category of disorders that is often described interchangeably with the broad spectrum of developmental disorders affecting young children and adults called the autistic spectrum disorders (ASD). The range of these disorders varies from severely impaired individuals with autism to other individuals who have abnormalities of social interaction but normal intelligence—Asperger’s syndrome. The ways in which autism is exhibited can differ greatly. Additionally, autism can be found in association with other disorders such as mental retardation and certain medical conditions. The degree of autism can range from mild to severe. Mildly affected individuals may appear very close to normal. Severely afflicted individuals may have an extreme intellectual disability and unable to function in almost any setting.
