If Newtons third law says there is an equal and opposite reaction how can there be energy transfer.
For example if I push a box and give it 1000 joules of energy wouldn't it "give back" the energy. Also does an object have to be moved for it to gain energy, if I were to punch a book many times would it gain energy or is it just giving back the energy becausE of Newtons third law. And if I drop a ball from a height of 10 feet wouldn't it gain energy after it hits the ground because I am supplying it with potential energy than it is converted into kinetic as it falls once it hits the ground the energy is transferred into the ground and then back into the ball therefore giving the ball more energy than when it started. Please correct me if I am wrong
