• Because two equal forces are acting on it in opposite directions 

• Because two equal forces and acting on it in the same direction 

• Because gravity is holding it up

Why does the egg move? 

• Because the downward force was increased leaving unbalanced forces 

• Because the upward force was removed leaving unbalanced forces 

• Because the downward force was removed leaving unbalanced forces  

What cause object to change their motion

• Balanced Forced

• Unbalanced Forces
