๐ What is Length?
Length tells us how long something is from one end to the other. Think about measuring how tall you are or how long your pencil is. We usually use tools like rulers or measuring tapes to find the length.
- ๐ Measuring tools for length include rulers, measuring tapes, and yardsticks.
- โ๏ธ Length is often measured in units like inches, feet, centimeters, or meters.
- ๐ถ You can estimate length by comparing an object to something you already know the size of (like your hand).
โ๏ธ What is Weight?
Weight tells us how heavy something is. It's how much gravity is pulling on it. To find the weight of something, we use scales. Unlike length, which measures distance, weight measures the force of gravity.
- ๐ Weight is related to mass, but they are not the same thing. Weight depends on gravity.
- โ๏ธ Common units for weight include ounces, pounds, grams, and kilograms.
- ๐๏ธ Scales are used to measure weight by showing how much force is exerted on them.
