Weights

What is Weight?

Weight is a measure of the heaviness of an object. Objects are categorized as heavy or light based on their weight.

When an object carries greater weight, it is considered heavy. For example, whales, hammers, trains and trucks fall into this category.

On the other hand, objects like feathers, paper clips, leaves and paper are considered light.

Measuring Weight

Measuring weight means finding out how heavy or light an object is. We use special tools to do this. These tools tell us how many grams or kilograms something weighs. So, if you want to know how heavy your favourite toy is or how much a bag of apples weighs, you can use a scale to find out.

Various types of weighing balances and scales are used to find the weight of an object.

A few examples are shown below:

The weighing balance operates using a simple principle. Within a weighing balance, you'll find two pans. The pan holding the heavier objects goes down, while the pan with the lighter objects goes up.

When the weight on each pan is identical, it signifies that the weight of both objects is the same.

Weight is represented using various units such as kilograms, grams, ounces, pounds, and so on.

Note:

• 1 kilogram (kg) = 1000 grams (g)
• 1 pound (lbs) = 16 ounces (oz)

Example: What is the weight of apples shown in the balance?

a) Heavier than 2 Kg
b) Lighter than 2 kg
c) Equal to 2 kg
d) Heavier than 3 kg

Answer: a) Heavier than 2 Kg

Explanation: In this question, the pan with apples goes down and the second pan with weight goes up. These weights are not equal level so the weight of the apples is heavier than 2 Kg.

Example: If the weight of 1 flower is 10 gm then, what is the weight of 4 such flowers?

a) 20 g
b) 30 g
c) 40 g
d) 50 g

Answer: c) 40 g

Explanation: Weight of 1 flower = 10 g
Weight of 4 flowers = 40 g
