A boy and a girl are pulling a heavy crate at the same time with 10 units of force each. What is the net force acting on the object ?

Sagot :

Tanong, same ba ang direction nila?

1.)Pag same ang direction nila:
   10 units of force         crate   -----------⇒    boy
+ 10 units of force                    -----------⇒    girl
    0 units of force  
 The net force acting on the object is 20 units of force.
 
2.) Pag opposite ang direction nila
                       
      <----------------  crate ------------------>
           boy                           girl
   (-10 units of force)         (10 units of force)

-10 + 10 = 0
 
 The sum of the forces is 0. There is no net force.
