Newton’s first law of motion
If the forces acting on an object are balanced then the resultant force of an object is zero
Newton’s second law of motion
The acceleration of an object is directly proportional to the force as force=mass*acceleration
E.g the higher the resultant force the more the acceleration
Newton’s third law of motion
When two objects interact with each other they exert equal and opposite forces on each other.

The journey to the promise land
Precambrian time, period of time extending from about 4.6 billion years ago (the point at which Earth began to form) to the beginning of the Cambrian Period, 541 million years ago. Precambrian time encompasses the Archean and Proterozoic eons, which are formal geologic intervals that lasted from 4 billion to about 541 million years ago, and the Hadean Eon, which is an informal interval spanning from 4.6 billion to 4 billion years ago. The Precambrian represents more than 80 percent of the total geologic record.
