What is a real life example of Newtons third law?

Answer 1

Rocket fuel pushing out the back of an engine (action) causes the rocket to move (reaction). A person jumps out of a light-weight canoe, the person goes one way, the canoe moves the other way.

Answer 2

A real-life example of Newton's third law is when you sit on a chair. As you sit down, you apply a force on the chair, and the chair applies an equal and opposite force on you. This is why you don't fall through the chair but instead remain seated.
