I love how you make fairly entertaining videos and explain physics problems in a way that makes sense unlike my textbooks..

Your videos are really helpful! They helped me do well on last year's Physics I exam.
Do you have a video series for AP Physics II?

Wow, the animations look so good! This will be such a useful video in learning/reviewing superposition. Thank you!!

Sir, I have a question that you can only answer to it ...please sir, in space, to push a ball of 200grams with 100 newtons for one meter...I have to push the ball for 0.063 seconds with 100 newtons, for producing work of 100 but for an truck of 50 tones, I have to push for 32 seconds with 100 newtons to push it one meter, to gain same amount of energy as ball gained. I surely have lost more energy on pushing truck(32 seconds of 100 newtons) than on pushing the ball (0.063 seconds of 100 newtons) BUT BOTH BALL AND TRUCK HAS THE SAME CHANGE IN KINETIC ENERGY....HERE LAW OF CONSERVATION OF ENERGY BREAKS....please explain this sir....

Are they posting the same video again and again or they're different?
