Man these videos are great, I have no idea why so many people don't explain it in minute details like you do. Kinematics for instance, you broke down rearranging them and which ones to use perfectly, while most people I watched just ran through the problems without explaining why they did anything.

Kudos to you sir, your work is appreciated.

I am so thankful that I found your videos in time, I think you honestly saved me from my exam, your explanation is easy and straight forward to the topic related, whereas I see my professor tends to explain the topic in wayy to much details, and it becomes really redundant information that I don't need. Thank you so much :)

aloha I’ve been watching these for better understanding do you have a way I can print you lecture so I can follow along with you?

Wait for question one if there was no force acting on the ball in the direction of its movement wouldn’t it just stop, is inertia not considered a force?
