It is difficult to fix a nail on a freely suspended wooden frame. Which law supports this statement?

Answer»

 NEWTON's third LAW



Newton's third law supports this statement.
When the wooden BLOCK is not resting against a support, the block and nails both MOVE forward on being hit with a hammer. However, when the block is held firmly against a support, and the nail is hit, an equal reaction of the support DRIVES the nail into the block.
