Force on Two Masses

Since F is the only net force acting on the two masses, it determines the acceleration of both:

The force F2 acting on the smaller mass may now be determined.
Note that by Newton's third law, the force F2 acts backward on m1. Note that the net force acting on m1 is consistent with the above.

Force on Two Masses


Add friction

 Application of Newton's second law to two masses.
For a force F= N applied to two masses m1=kg and m2=kg which are in contact with each other, the acceleration is given by
= m/s²
Then the force exerted on mass m2 can be determined.
= N
