Question

Name and state the action and reaction in the following cases
1 firing a bullet from a gun
2 hammering a nail
3 a book lying on the table
4 a moving rocket
5 a person walking on the floor
6 a moving traun colliding with a stationary train
7 pulling of a cart by horse

Answer 1

1. Action : The bullet moves forward
Reaction : The recoiling of gun ( The gun will move back as the bullet goes forward )

2. Action : The nail goes into the material
Reaction : There will be a force acting on the hammer ( that is why it vibrates and gets a little hot )

3. Action : The book is acting a force on the table due to gravity
Reaction : There will be an upward force applied by the table ( that is why the book is in rest on the table ; both the forces will get cancelled )

4. Action : There is huge outflow of gases and burnt fuel
Reaction : The rocket moves forward

5. Action : The person applies a force on the floor
Reaction : The floor applies an equal force back ( that is why he moves )

6. Action : The moving train hits the stationary one and it moves back
Reaction : The stationary train applies a force back to the moving one and it stops ( as a result the moving train stops and the stationary one starts moving )

7. Action : The horse applies a force on the floor
Reaction : The floor applies an equal force back ( that is why horse and the cart moves )
