Newton's Laws of Motion

1. Sir Isaac Newton

1.1. 1642 – 1727

1.2. English physicist & mathematician

1.3. Philosophiæ Naturalis Principia Mathematica

1.4. Laid the foundation for classical mechanics

2. 1st Law

2.1. Formula

2.2. The Law of Inertia

2.3. An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

3. 2nd Law

3.1. Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

3.2. The Second Law gives us an exact relationship between force, mass, and acceleration. It can be expressed as a mathematical equation:

3.2.1. FORCE = MASS times ACCELERATION

4. 3rd Law

4.1. For every action there is an equal and opposite re-action.

4.2. Formula
