Newton’s Laws of Motion
Isaac Newton
1. Every body continues in its state of rest or of uniform motion in a right line unless it is compelled to change that state by forces impressed upon it.
2. The change of motion [acceleration] is proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed.
3. To every action there is opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal and directed to contrary parts.
