Balanced and Unbalanced
this is a balanced force because they are pushing with the same amount of nutens which caused it not to move. if one pushes with 60 and the other pushes with 60 the net force is 0
this is balanced force because the table pushes up with20 nutens and the block pushes down with 20 and keep the block from moving if the net force 0
this is unbalanced the ball roles down hill with 120 nutens and friction is 23 the net force is 97
this is a unbalanced force if the thrust from the engine 606 nutens and the weight 120 the net force is 486
