Sir Isaac Newton was born in 1642 and later died in 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.

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.”

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 Newton’s 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 car’s original speed. This is why a seatbelt is required so you don’t keep traveling into the windscreen and hence an object (you in a car) will stay at rest unless acted upon by another force.

Stay in motion (same speed and direction)
