Types of Disability
There are three types of disabilities which are as follows

[i] Cognitive Disability
The nature of this disability is mental since cognitive domain is related to using mental abilities and achieving results from it.
It is related to impairments in intellectual functioning and adaptive behaviour. Intellectual functioning means person’s ability to plan, comprehend and reason while adaptive behaviour refers to applying social and practical skills in everyday life. Children suffering from dyslexia, learning difficulties, speech disorders, problem in solving math calculations, short span of attention and short of memory are said to have cognitive disability.
Causes of cognitive disability are as follows

• Cognitive impairment may be present at birth and may be genetic or chromosomal or result from complications of pregnancy.
• Chromosomal abnormalities such as Down syndrome, fragile X syndrome.
• Genetic abnormalities such as phenylketonuria, Hunter syndrome etc.
• Prenatal drug and infections and exposure to alcohol.
• Lack of oxygen during labour pain or birth.

[ii] Intellectual Disability
The nature of this disability is also mental since the intellectual domain is related to using the capacity of the mind. It is a disability characterised by significant limitations in both intellectual functioning and in adaptive behaviour. This is characterised by low intelligence quotient score (under 70) and significant problems in the ways learners adapt to new situations. It is different from cognitive because cognitive is a broad concept while intellectual disability is specific in nature.
Causes of intellectual disability are as follows

1. Genetic Conditions These include things like Down syndrome and fragile X syndrome.
2. Problems during Pregnancy This can interfere with fetal brain development.
3. Alcohol or Drug Use may also cause intellectual disability.
4. Problems during Childbirth Like if a baby is deprived of oxygen during childbirth or born extremely premature.
5. Illness or Injury Infection like meningitis, whooping cough or measles can lead to intellectual disability. Extreme malnutrition, infections in the brain, exposure to toxic substances such as lead, and severe neglect or abuse can also cause it.

[iii] Physical Disability
The nature of this disability is physical since it relates to physical functioning of the body parts including sense organs.
This refers to the limitation on a person’s physical functioning, mobility, dexterity or stamina. This includes upper or lower limb loss, poor manual dexterity, visual impairment, hearing loss or disability in coordination with different organs of the body. Apart from these, respiratory disorders, epilepsy and sleep disorders are also considered physical disability.
Causes of physical disability are as follows

• Illnesses like cancer, heart attack or diabetes cause the majority of long-term disabilities.
• Back pain, injuries and arthritis are also significant causes.
• Lifestyle choices and personal behaviour that lead to obesity are also becoming major contributing factors.
• Musculoskeletal disorders also cause disabilities. Examples include spine/joint disorders, fibromytis etc.
• Genetic causes like gene inheritance can cause this disability.

Meaning of Physical fitness: Physical fitness means the capacity to do the routine work without any fatigue or exertion and after doing the work the person has power to do some more work and recovery is quicker.

According to Charles A Bucher, “Physical Education is an integral part of total education process and has its aim the development of physically mentally, emotionally and socially fit citizens through the medium of physical activities which have been selected with a view to realize these outcomes.

According to Cassidy, “Physical education is the sum? of changes in the individual caused by experience which can bring in motor activity.

Olympic flag is made of white silk and contains five interlocking rings/circles in five colours representing five continents of the world namely America, Europe, Australia, Asia and Africa. 

The rings are five interlocking rings, coloured blue, yellow, black, green and red on a white field, known as the "Olympic rings". The symbol was originally created in 1913 by Coubertin. He appears to have intended the rings to represent the five continents: Europe, Asia, Africa, The Americas, and Oceania.

let's look at the roles of a teacher. In short, a teacher teaches, but they also design the educational content to pass knowledge to students. Teachers are responsible for assessing students' learning and skills through testing or other assignments designed to illustrate the students' abilities. Through these assessments, teachers are often expected to identify at-risk students and bring those students to the attention of the proper departments within the school.

In short, a teacher is much more than a person who presents information.

Now, what is the role of a special education professional? A special education professional's roles include those of a traditional classroom teacher and of a support service provider. The difference between a special education professional and a mainstream teacher is that the special education professional performs all duties with and for students with varying degrees of disability and not all duties are related to teaching. All teachers must be aware of laws that regulate the education environment, but special education professionals must also be aware of the laws pertaining to people with disabilities. As we discuss special education professionals, we should first discuss their responsibilities to their students as vulnerable individuals.

Newton’s First Law of Motion also known as Law of Inertia states that every object persists to stay in uniform motion in a straight line or in the state of rest unless an external force acts upon it.

Newton’s Second Law of Motion states that force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration, i.e. F = m*a. Learn about the Acceleration in detail here.

Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction.

Riding a bicycle is a good example of Newton’s 2nd law. In this example, the bicycle is the mass. The leg muscles pushing on the pedals of the bicycle is the force.

The motion of a ball falling through the atmosphere, or a model rocket being launched up into the atmosphere are both excellent examples of Newton’s 1st law.

The Olympic ideals that Cubertin set before the world are enshrined in these words.
“The important thing in the Olympics is not to win but to take part. The important thing in life is not the triumph but to struggle. The essential thing is not to have conquered but fought well”.

1) Healthy diet : A healthy diet and good nutrients is one of the main components of a positive lifestyle. It is also beneficial to minimize the saturated fats and food laden with sugar and salt.

2) Physical Activity:  Physical activity or exercise is another vital component of positive lifestyle. Regular physical exercises are needed to maintain a healthy weigh and to enhance strength and flexibility of the body.

3) Stress Management:  Stress management is also a significant component of positive lifestyle. Stress can be manage properly through meditation and relaxation techniques only.
