Question

examples for newton's third law of motion

Answer 1

throwing a ball towards wall

Answer 2

while walking we press the ground with our feet slanted in the backward direction. The ground exerts an equal and opposite force on us. The vertical component of reaction force balances our weight and the horizontal component provides us forward motion.


Let us consider a block suspended by the string. Earth exerts force on the block, the equal amount of force is exerted by the block on the earth. Similarly block does action on the support through string, the equal amount of reaction is exerted by support on the block.
In this case action and reaction are equal to mg.
