4. A rock is thrown straight upward with a velocity v. What is its acceleration at the top of its path? What is its velocity when it comes back to the starting point? Why?

At the very top of the path, where the velocity is equal to 0, the acceleration will be -9.8 m/(s*s), the acceleration of gravity. It will no longer have any upward acceleration. When it comes back the its starting point (assuming that it is the ground) its velocity will be equal to 0 because its downward progress will be stopped by the ground

Tutor: What is the velocity just before it hits the ground?

Student: That will depend on the time that the ball is in the air/distance ball traveled.

Tutor: How will it compare with the velocity with which it was thrown up?

They will be equal.The height the ball reaches will depend on the initial velocity

Example Dialogue with Emotion Labels

Tutor: Now this law that force is equal to mass times acceleration, what's this law called? This is uh since this it is a very important basic uh fact uh it is it is a law of physics. Um you have you have read it in the background material. Can you recall it?

Student: Um no it was one of Newton's laws but I don't- remember which one. (laugh) (EMOTION = NEGATIVE (uncertain))

Tutor: Right, right- That- is Newton's second law of motion.

Student: he I- Ok, because I remember one, two, and three, but I didn't know if there was a different name (EMOTION = POSITIVE (confident))

Tutor: Yeah that's right you know Newton was a genius-

Student: (laugh) (EMOTION = POSITIVE (amused))

Tutor: and uh he looked at a large number of experiments and experimental data that was available and from that he could come to this general law and it is known as Newton's second law of motion. Um many many other scientists before him had seen all this data which was collected by scientists but had not concluded this now it looks very simple but to come to the conclusion from a mass of data was something which required the genius of Newton.

Student: mm hm (EMOTION = NEUTRAL)

Tutor: So now you will give Newton full credit isn't it? (laugh)

Student: (laugh) (EMOTION = POSITIVE (amused))
