Thank you a lot for your helpful videos. This channel is really underestimated in its potential, producing such a quality content with great explanations and slides but having so few views and likes. I wish more learners knew about existence of this channel :(
Thank you for your efforts. You are doing an amazing job. Thank you so much. I have a doubt and I hope you will clear. When you consider the two objects to be as one system adding their masses, shouldn't the mass of the rope be added which is unknown? If the objects are big enough compared to the mass of the rope, the mass of the rope can be negligent but still might affect the calculation to a small degree. But what about objects of small masses that are attached by the rope, won't the mass of the rope have significant effect on the total mass of the system? I hope I am clear.
Yes. The rope's mass should also be included. Yet it's mass is often so small relative to the objects' mass that neglected its mass has little impact on the final result.
In step2, when analyzing the contact forces between the two objects, though the force is applied to one of the objects, won't that force get transferred to the other object too? That is why both the objects are moving at same acceleration right? Then why is that we leave the applied force when drawing FBD for the object where the force is not applied directly? Thanks for all your replies.
@@PhysicsclassroomVideos Sorry to ask you more questions. The force that the object pushes on object 2 is equivalent to the force applied on object 1, is it not so? That is why both are accelerating with the same rate right? So the same magnitude of force on object 2 should be considered right? If not, why is it not considered?

I do to. Thanks for your kind words.
Thank you! This was really helpful to me while studying for my physics Exam.
I have just discovered your channel. I liked it so I subscribed to follow your videos. Thankfully 😅
Thank you! My physics teacher is awful-this video helped me immensely!
You're very welcome!

@@PhysicsclassroomVideos Thanks for your prompt replies. I appreciate it.
very well explained 🥰

No. The force is exerted only on the object you touch ... not on the object you don't touch.
@@PhysicsclassroomVideos In physics point of view, how do we explain the motion of the object where force is not exerted by touch but by the contact?
A person pushes on object 1. Object 1 then pushes on object 2. It's the force of object 1 pushing on object 2 that effects the motion of object 2.

what do you use as reference book? thank you so much!
I have several different HS and college Physics textbooks.
