Question

Kristina fixed nails on a wooden piece using a hammer. Which type of force did Kristina apply on the hammer?​

Answer 1

Answer:

Muscular force

Damm easy

Answer 2

Kristina applied muscular force on the hammer.

• The muscular force only helps when there is a frictional force in this case.
• When Kristina applies muscular forces on the hammer to hit, friction comes into the picture.
• According to Newton's third law of motion, "every action has an equal and opposite reaction."
• The nail hit by the hammer exerts some force backward such that the hammer stops at a point when hitting the wall.
