- HI JOEY, YOU KNOW THESE DAYS I AM STUDYING ABOUT GRAVITATION IN SCHOOL BUT I AM SOME WHAT CONFUSED ABOUT THE DIFFERENCE BETWEEN MASS AND WEIGHT. CAN YOU PLEASE EXPLAIN THAT TO ME?
- YA SURE, LET'S TALK ABOUT MASS FIRST. MASS IS THE MEASURE OF THE AMOUNT OF MATTER IN A BODY.MASS IS DENOTED BY “M”.
- MASS IS ALWAYS CONSTANT FOR A BODY AND THERE ARE SEVERAL FORMULAS TO CALCULATE MASS.ONE WAY TO CALCULATE MASS IS:MASS = VOLUME × DENSITY*MASS ONLY HAS MAGNITUDE AND SO, IT IS A SCALAR QUANTITY.THE SI UNIT OF MASS IS KILOGRAM (KG).
- THAT WAS PRETTY INTERESTING. AND WHAT ABOUT WEIGHT.
- YES, LET'S TALK ABOUT WEIGHT NOW.
- WEIGHT IS THE MEASURE OF THE AMOUNT OF FORCE ACTING ON A MASS DUE TO ACCELERATION DUE TO GRAVITYWEIGHT IS DENOTED BY “W”
- WEIGHT IS THE MEASURE OF THE GRAVITATIONAL FORCE ACTING ON A BODY.WEIGHT CAN BE CALCULATED FROM THE FOLLOWING FORMULA:WEIGHT = MASS × ACCELERATION DUE TO GRAVITYWEIGHT HAS BOTH MAGNITUDE AND DIRECTION (TOWARDS THE CENTRE OF GRAVITY) AND SO, IT IS A VECTOR QUANTITY.THE SI UNIT OF WEIGHT IS NEWTON (N).
- THIS WAS REALLY VERY HELPFUL. THANK YOU SO MUCH.
- YOU'RE WELCOME
