00:00hi kids today we will learn what is mass so let's get started
00:09the mass is the amount of matter that a thing contains the units of measuring
00:17mass are kilograms and grams where one kilogram is 1,000 grams in everyday
00:32usage we refer to mass and weight as one and the same thing but in fact mass and
00:42are different quantities mass refers to the amount of matter in an object and
00:50weight refers to the force experienced by an object due to gravity mass of
01:02objects always remains the same but the weight of objects can change depending
01:08on where you are like for example your weight on earth will be different from
01:18your weight on the moon we will study more on the difference between mass and
01:26weight in science for now we will remember we measure mass or weight of
01:36solid objects in grams or kilograms and we measure weight of liquid objects in
01:46milliliters or liters and we also measure capacity of objects in liters
01:55now let's learn more about mass or weight here is a feather its weight is about just one gram
02:10we write it like this here's a disposable spoon its weight is about five grams we write it like
02:25this here is a packet of some eatable that weighs about 25 grams here is a small gift weighing 50
02:40grams here are examples of some things weighing 100 grams here is a cake weighing about 500
02:55grams 500 G here is an object weighing 1 kilograms or 1 kg so we calculate the mass of objects by
03:12measuring its weight now let's try to remember a few things 1 kilogram is 1,000 grams 500 grams
03:27is half kg 500 grams plus 500 grams will be 1,000 grams or 1 kilogram 2 kilogram is 2,000
03:49grams 3 kilograms is 3,000 grams good so kids today we learn what is mass and how to measure
04:04it now you may go ahead and take a quiz to learn more bye bye
