DIFFERENCE B/W MASS AND WEIGHT|ACCELERATION|VELOCITY|SPEED FOR JKSSB &JKPSC

📘 MASS, WEIGHT, SPEED, VELOCITY & ACCELERATION | PHYSICS BASICS
In this video, we explain the basic concepts of Physics including Mass, Weight, Speed, Velocity, and Acceleration in a clear and easy-to-understand manner.
Special focus is given to the difference between mass and weight and the real-life use of velocity and acceleration.
This lesson is very helpful for school students as well as competitive exam aspirants.
🔹 Why should you study these topics?
• These are foundation topics of Physics
• Frequently asked in board exams and competitive exams
• Required to understand motion, force, and laws of motion
• Helps in solving numericals and MCQs
• Used in daily life applications like vehicles, sports, and motion analysis
🔹 What is taught in this video?
• Meaning of Mass
• Meaning of Weight
• Difference between Mass and Weight
• Speed and its concept
• Velocity and its direction-based nature
• Acceleration and change in velocity
• Real-life applications of velocity and acceleration
• Concept clarity with simple explanations
🔹 Important Points (Easy Understanding):
• Mass remains constant, weight changes
• Speed has only magnitude, velocity has magnitude and direction
• Acceleration tells how fast velocity changes
• Used in daily life like driving, running, braking, and motion of objects
