Newton's laws of motion for your convienience.

The three laws of motion are:
1) An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an outside force.
Example: A person keeps going even when his/her car abruptly stops are stopped by the outside force, a seatbelt or a windshield.
2) An object will accelerate in the direction a force moves it.
The equation being F=MA, force= mass times acceleration.
Example: A soccer ball goes in front of you becuase you kicked it that way.
3) For every action there is an opposite but equal reaction.
Example: You crash into a wall and according to this law you would bounce backwards.

ALL OBJECTS IN THE WHOLE UNIVERSE OBEY THESE LAWS OF MOTION. OBJECTS ARE THINGS LIKE PEOPLE, PLANTS, STARS, RACERS, OR GALAXIES.

Velocity is how fast something is going or its speed. To find it you use this equation:
V = D/T, velocity = distance over time. it is usually measured in miles per hour like a car.
Acceleration is how much a speed increases or decreases over time. The equation is:
A= delta V / t. acceleration = the change of velocity over time.

There are two types of motion, uniform and accelerated.
Uniform: Relates to the force law. An object is at rest or keeps moving in one and only one direction.
Accelerated: An object moves in any direction and can increase or decrease.

Units to measure in:
Acceleration: meters per second squared, etc..
Velocity: meters per second, etc...

Sir Isacc Newton mainly built upon the ideas of previous scientists. The most known person who contributed the most to this topic was Gallelio Gallilei. He was the first to discover that the planets rotated around the sun.
