- Good day everyone. I'm your local researcher, Daisy, and I'm here to talk about action-reaction phenomena.
- Newton's Third Law of Motion states, “When one object exerts a force on a second object, the second one exerts a force on the first that is equal in magnitude and opposite in direction.”
- Despite the fact that the forces are of equal magnitude and opposing direction, they do not cancel out. This law applies to two objects, each of which is subjected to only one force; each object exerts only one force on the other; each object is subjected to only one force.
- An example would be a person swimming forward. The swimmer pushes against the water (action force); the water pushes back on the swimmer (reaction force) and pushes them forward.
- Ball
- Another can also be a ball being thrown against the wall; The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
- What about walking?
- So Daisy, is a book lying on a table an example of action-reaction?
- Yes, of course. Each step consists of a backward push to the ground, which causes the ground to respond by pushing us forward, which is why we move forward.
- Yes, The weight of the books is pushing down on the table. This is the action, in which the table's reaction acts upward on the books.
- There you have it folks; Newton's Third Law of Motion.
- I hope you learned a bit about our topic and I'll see you all next time!
