Why action and reaction are equal and opposite but even they do not cancel each other?

This is because acceleration depends on both force and mass (F = ma).

We know that from Newton's Third Law. While action-reaction forces are always equal, the objects they act on usually have very different masses.

If you consider a falling stone and the Earth as an action-reaction pair. The Third Law

The third law of motion by Newton may confuse you into thinking that action causes reaction in sequence. This is incorrect.

In reality, both forces exist at the exact same moment. When you push a wall, your hand pushes the wall. At the same time, the wall pushes back simultaneously. Not one, then the
