Newton's Laws
Glenbrook: Newton's 1st Law of Inertia: gifs
A vertical force moves the wagon horizontally.
The force of gravity on  1.0 kg or 1000 g = 9.810 newtons or 2.2 lbs of force.
Graph F vs  A for 3 different wagons: Record the data and use Graphical Analysis to plot graphs
.
Let hanging mass =
1,2, or 3 g and calculate gravity force, record acceleration and graph it for 100 g   (0.100 kg)            
wagon.  Graph
F vs A (force on the vertical axis). Record slope.  Calculate the equation of   the line and put on the           
graph.Also put the mass of the cart in
Kg on the line
Change mass of the wagon to
200 g and use hanging mass 1,2,3 g...record A and graph F vs A and record slope              
again. Put mass of the cart in Kg on the line also.
Repeat for
400 g wagon . Record slope. Find the equations of the line and put on the graph along with the mass in Kg.
Conclusion: What seems to be the relationship between Pulling Force, Mass being pulled and Acceleration?  Based on t      
 his lab what is a Newton equal to?  
Summarize the whole lab in words and then (if you can) an equation> 30 pts

2.   F=ma practice the 2nd Law: Frictionless...calculate the acceleration and check your answer. Later
change the coef. of friction and calculate the acceleration and check your answer.
...Rollover car crashes
3.  Set one block to Zero and you can use static and kinetic friction on an inclined plane
                       Comparison of Static and Kinetic Friction with some neat graphs
Calculate time it takes to go  down a plane: use vector components...more difficult

An Internet Lab
      See how acceleration is related to mass and force
1.   If Σ F=0 then Velocity is constant
2.   F net / Mass    =    Acceleration
3.   Force of A on B = - Force of B on A
