Third law: When a first body exerts a force F1 on a second body, the second body simultaneously exerts a force F2 = -F1 on the first body. This means that F1 and F2 are equal in magnitude and opposite in direction.
but suppose
mass 1 = 1 kg
mass 2 = 2 kg
and they both have an acceleration of 1 m/s^2
magnitude of f1 = m1*1m/s^2 = 1 kg-m/s^2
magnitude of f2 = m2*1m/s^2 = 2 kg-m/s^2
f1 and f2 are not equal in magnitude!
And your numbers are wrong. You are showing 2 different forces.
force is the product of mass x acceleration
it doesn't say that the two bodies have equal mass
or equal velocity.
that's why I used two different forces.
But the 2 bodies will have the same force exerted on them, just in opposite directions.
that's impossible.
unless you plan ahead of time and adjust the accelerations
of the two masses or the mass of the two masses or both to achieve the same force.
2 bodies experiencing a force of the same magnitude but with different masses will experience different accelerations.
I can agree to that.
