What does action reaction force mean? BYJU'S QnA
Actionreaction force: An action force is a force that is applied to an object A reaction force is a consequence of an action force which is opposite in direction Newton's third law of motion deals with these two forces, which are known as action and reaction forcesCarbon dioxide (CO 2), another emission resulting from burning coal, is a major greenhouse gas that is associated with global warming (see Chapter 13 ) Burning of coal is classified as incomplete combustion, since the reaction of 156: Coal The Carbon Rock of Ages Chemistry Fossil fuels form over millions of years from the burial of photosynthetic organisms, including plants on land (which primarily form coal) and plankton in the oceans (which primarily form oil and natural gas) To grow these organisms removed carbon dioxide from the atmosphere and the ocean, and their burial inhibited the movement of that carbon through the carbon cycleBurning of fossil fuels Understanding Global ChangeLet’s think about an example: when you push on a box, the box pushes back on you Your push on the box is the action force The force from the box on you is the reaction force The two forces have the same strength, but they act in opposite directionsAction and reaction forces Khan Academy
