About Newton
Sir Isaac Newton was born in 1642 and later died
in 1727. Newton was an english mathematician,
physicist, astronomer, alchemist, chemist,
inventor, and natural philosopher. He was one of
the most scientific intellects of all time. Born
at Woolsthorpe, near Grantham in Lincolnshire
where he attended school.

Newton's First Law
INERTIA
The law of Inertia in often stated as An
object at rest tends to stay at rest and an
object in motion tends to stay in motion with the
same speed and in the same direction unless acted
upon by an unbalanced force.

An object at rest tends to stay at rest and an
object in motion tends to stay in motion with the
same speed and in the same direction unless acted
upon by an unbalanced force.
Summarising this law in short it says that an
object will keep doing what its doing until
another unbalanced force acts upon the object. A
good example of Newtons first law is when you
are in a car and suddenly the brakes are applied,
the car screeches to a stop but your body
continues to move forward assuming your not
wearing your seatbelt. Because there is a force
on the car but not on you, you continue to travel
forwards while the car stops but you are simply
just staying at the same speed as the car was
going but because the car is now stopping
it seem that you have been flung into the
windscreen but all that is happened is the car
has started to decelerate and you are still
travelling the cars original speed. This is why
a seatbelt is required so you dont keep
traveling into the windscreen and hence an object
(you in a car) will stay at rest unless acted
upon by another force.
