Beginner Physics: Learn the Basics Now!

AI Thread Summary
The discussion centers on understanding kinematic equations in physics, specifically regarding distance, initial speed, and acceleration. A participant expresses confusion about distinguishing between initial and final velocity, particularly when "rest" is not mentioned. Clarification is provided that if the initial speed is stated as 6 m/s, then that is the initial velocity. The conversation highlights the importance of correctly identifying terms in kinematic equations for solving physics problems. Overall, the thread emphasizes the need for clarity in understanding basic physics concepts.

So you have the distance, initial speed and acceleration.

Which kinematic equation has all these terms in it?
 
Haha, actually I think I was confused by the velocity. I didn't know whether it was initial or final. I just got the answer. Thank you! Btw, is it initial if "rest" is not stated in the equation?

well it said from 6m/s, so initial velocity = 6
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...

Thread 'A bead-mass oscillatory system problem'

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
