Projectile Motion
This lesson covers the definition of projectile and projectile motion. It explains the concepts of time of flight, maximum height, and range, along with the relevant equations and examples from sports and warfare.
- 08:03 “And vertically, U is U sin theta. So why is substitute for that? We have 0, 0 squared is 0 equal to U sin theta all squared minus 2G H. So bringing to G H to this place, we have 2G H plus 2G H equal to this U squared sin...”
- 06:27 “So we have T equal to 2U sin theta over G. So that's our time of flight as it is. If the time taking to reach the maximum height is T1, and T2 is the time taking to return to the plane of projection, so T1 equal to T2 eq...”
- 07:13 “The maximum height is represented with capital letter H. The highest vertical distance attained by projectile as measured from the horizontal plane of projection is the highest vertical distance attained. So our H to fin...”
Cost of Production
This lesson covers the concept of cost in economics, focusing on the cost of production. It explains different types of costs, such as fixed and variable costs, and discusses the factors of production that contribute to overall costs.
- 32:14 “6. Is MC greater than AC? No. 2. 5. Is MC greater than AC? No. 10. 6. MC here is greater than AC here. So where does it start? As what output? As what output? 5. So you tell them MC starts to be greater than AC as well a...”
- 31:22 “From 5, it's increasing to 6. So as what's output? You trace it. Trace it. What do you have there? Five. So you will tell them AC starts increasing at output five. AC starts increasing at output five. I will put together...”
- 30:30 “So you will give them the answer according to the demand of the question. The first one says as what output is AC at the minimum? This is your AC. What's the minimum AC up? Yes, five. Trace it to your quantity. Four. AC...”
