Question

newtons third law of motion states that for every action, there is an equal and opposite reaction. it is also called the law of action-reaction. an action force is a force acting in a specific direction. a reaction force is a force acting in the opposite direction as another force. action-reaction forces act in pairs and are equal and opposite. when you jump up in the air, the action force is your feet pushing down on the floor and the reaction force is the floor pushing up on your feet. choose the correct answer which of these is an example of newtons third law of motion? taking a nap and not moving pushing your feet onto the ground and jumping up into the air using light to read a book

Explanation:

To determine the example of Newton's Third Law (action - reaction: equal and opposite forces in a pair), we analyze each option:

• "taking a nap and not moving" shows no force interaction related to action - reaction, so it's incorrect.
• "pushing your feet onto the ground (action force) and the ground pushing back to make you jump (reaction force)" follows the action - reaction pair concept of Newton's Third Law.
• "using light to read a book" involves light - matter interaction, not force pairs as per Newton's Third Law.

Answer:

pushing your feet onto the ground and jumping up into the air
