(m) a    Fnet (N)
(s2) m  (Kg)

 


2.  The acceleration a given force will produce on an object is inversely proportional to the mass of the object

 


F = 10 nt 
  
  F = 10 nt 
m = 2 kg 

m = 4 kg
 
a = 5 m/s2 
a = ? 
 

a = 5 m/s
2 

 a = 2.5 m/s2

                                            
                                            
                                           

 

Double the mass,
half the acceleration
 

 

 

x2 x1/2



x1/2 x2



x1/3 x3



x3 x1/3



x1/4 x4



x3/2 x2/3



 

Why do all bodies accelerate at a rate of 10 m/s2 (9.8 m/s2) 

 

 3. Inertial mass (solve for m) - Finding mass using motion and force

 

m  =    Fnet
a 

  

 

What is the mass of the body that produced the plot above?

 

m  =  Fnet = 6 N
a  2 m/s2

 

m = 3 kg
