Newton's Third Law: Why Is There Motion?

AI Thread Summary
Newton's third law states that for every action, there is an equal and opposite reaction, which applies to different bodies and does not cancel out. This law does not prevent motion; instead, it explains how forces interact during collisions, such as when two blocks collide. When one block hits another, it moves due to inertia, while both blocks experience equal and opposite forces. The center of mass of the system may not move, but the individual objects can still exhibit motion. Thus, motion is consistent with Newton's third law, as it accounts for the dynamics of interacting bodies.

I was wondering, if Newton's third law is true why is there motion?

Why do you think that Newton's 3rd law would prevent motion? Note that the equal and opposite forces mentioned in Newton's 3rd law act on different bodies, thus they don't cancel--if that's what you're thinking.
 
According to the third law.if two blocks collide each other. they apply force on each other by equation F=-F.
note:when block hits another block. it moves when it collides with Inertia.
 
Newton's third law includes reaction forces. When an object is accelerated, it reacts with an opposing force equal in magnitude to the force accelerating it.

actually
It says there is no motion of their centre of mass.

But there IS motion of the the 2 individual objects. Obviously.
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
