Unit 3
Forces & Newton’s Laws of Motion

7. Described as a Natural Philosopher
Sir Isaac Newton
1643 – 1727 England
Described as a Natural Philosopher
Mathematician, Physicist, Author, Astronomer.
Created Calculus
Founded the Laws of Motion & Law of Universal Gravitation.

8. Force
A force is a push or pull acting upon an object as a result of its interaction with another object. There are a variety of types of forces. Force is a Vector quantity.
Measured in Newtons [N]
Types of Forces:
Frictional Force
Tension Force
Normal Force
Air Resistance Force
Gravitational Force
Magnetic Force
Etc.

9. Friction
Friction is the resistance to motion of one moving object relative to another.
Types of Friction:
Static Friction – Force that keeps an object at rest. Must be overcome to move an object
Kinetic Friction:
Sliding Friction – Force that resists the movement of a sliding object
Rolling Friction – Force that resists the movement of a rolling object
Liquid Friction – Force that resists the movement of an object through a liquid

10. Newton’s Laws of Motion
First Law – An object in motion or at rest will remain in motion or at rest until acted on by an outside force
Second Law – F = ma
Third Law – For every action, there is an equal but opposite reaction

11. Inertia
The tendency to do nothing or to remain unchanged
Represented by Newton’s 1st Law of Motion

12. Free Body Diagrams
Also known as Force Diagrams
A universal way of notating and communicating Forces acting on an object.
Net Force (Sum of Forces) – A numerical combination of all forces acting on an object.

13. Balanced & Unbalanced forces
Balanced forces – Will NOT move an object
Normal Force – Book sitting on a desk
2 students applying equal forces to opposite sides of a box
Unbalanced forces – Will move an object
1 student pushing a box, accelerating it
A ball falling through air
