Lec-3: Physics 1st Paper Chapter 5 | কাজ শক্তি | অভিকর্ষ বলের বিরুদ্ধে h উচ্চতায় উঠাতে কৃত কাজ | Azam's Classroom

Description:
Welcome to Azam's Classroom! In this third lecture of Chapter 5 from HSC Physics 1st Paper, we discuss the topic অভিকর্ষ বলের বিরুদ্ধে h উচ্চতায় উঠাতে কৃত কাজ (Work Done Against Gravitational Force to Lift an Object to Height h). This lesson is crucial for understanding how work is calculated when an object is moved vertically against the force of gravity, a key concept for HSC Physics students.

In this video, you will learn:

The physics behind gravitational force and how to calculate the work done to lift an object.
Formula: W = mgh (where m = mass, g = gravitational acceleration, and h = height).
Real-life applications of this concept in elevators, cranes, and lifting objects.
Step-by-step problem-solving techniques to help you master HSC Physics exam questions on this topic.

Problems Covered in This Video:

Calculate the work done to lift a 10 kg object to a height of 5 meters against gravity.
Determine the energy required to lift an object to a height of 20 meters if the mass is 15 kg.
Solve a real-life example of calculating the work done by a crane in lifting materials to the top of a building.

This video is designed to provide you with a clear understanding of work done against gravitational forces, making your HSC exam preparation easier and more effective.
