Fun with Forces

     In class we started a new unit called Newton's Laws of Motion and Forces. We started class by talking about what we new about Newton's laws and forces. 
      We found that force is a push or pull that may cause the object to:

• change its shape
• accelerate
• or not change in any way

We also found that there are four types of force which are:

1. Applied Force- is a force applied to an object by another object
2. Force of Gravity- Fg= 9.8 m/s2 which the downward force exerted on objects on earth
3. Normal Force- the force applied to an object which is on another stable object (ex. labquest on a table)
4. Friction Force- is a force applied to an object by a surface as it either moves or tries to move across that surface.

     We also started to learn how to draw free body diagrams, which allow you to show the forces applied to an object. 
Ex. Draw a free body diagram for a Hemi Cuda driving west on the highway. 

The Cuda has the forces of gravity, normal, friction and applied so the free body diagram would look like

We will be continuing to learn about free body diagrams in the next class.

Next is Indianna.
