(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

 

[ Flash ]

 

 


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)"

(neglecting friction)

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
