Answer 2

The classification of the given situations as balanced and unbalanced force are:

1. a man pushes - Unbalanced Force

2. boy bats the ball - Unbalanced Force

3. air rushes down - Unbalanced Force

4. hammer pushes a nail​ - Balanced Force

Here are the reasons why:

• Equal in size and directed in the opposite direction, balanced forces are. When forces are evenly distributed, motion remains unchanged.
• Here in 1. a man pushes, this could be both balanced or unbalanced force. For eg: If the man pushes a rock and its motion is unchanged, it is a balance force where as if the man pushes a chair and it moves it is unbalanced.
• Similarly, in 2. a boy bats the ball, the ball would move towards a direction is batted and will follow projectile motion. Hence, it is unbalanced.
• In 3. air rushes down is also a unbalanced force.
• Hammer pushes a nail is a balanced force because the wall applies the same and opposite force on the wall which makes it difficult to barge inside.
