Newton’s Second Law –Part (II)

1. a)

 

Item

Mass( )

Glider  
Small Weights        
Large Weights        

Glider length : _________________

6. b) iii

Print out a good oscilloscope graph (the trace of the force voltage vs. time).

6. c) ii & iii

Record the time and calculate the velocities :

(velocity = glider length / time)

Notice : the positive velocities and forces are measured to the left.)

(Momentum change ΔP= Pf – Pi =m( vf – vi ) )

Total glider mass used in the collision = ______________

 

 

Time ( )

Velocity ( )

Momentum( )

Before collision

     

After collision

     

 

Momentum change ΔP= _______________

 

7. e) Record the results of the integration:

  1. Print out the “Force v.s Time” graph.

 

8. Compare the “momentum change” with the measured “Impulse”.

9. Repeat the experiment with adding weights to the glider:( Don’t need to print out any graph.)
