FAQs on Textbook: Mass (Term 3) - Mathematics for Grade 6

1. What is mass, and how is it different from weight?
Ans.Mass is the measure of the amount of matter in an object, usually measured in grams or kilograms. It is a scalar quantity and does not change regardless of location. Weight, on the other hand, is the force exerted by gravity on that mass and can vary based on the gravitational pull of the environment, measured in newtons or pounds.
2. How do you measure mass in a laboratory setting?
Ans.Mass can be measured using a balance or scale. In a laboratory, a balance compares the mass of an object to known masses, providing an accurate measurement. It is essential to ensure that the balance is calibrated correctly and that the object is placed in the center of the balance pan.
3. What are some common units of mass?
Ans.Common units of mass include grams (g), kilograms (kg), milligrams (mg), and metric tons (t). In the Imperial system, mass is often measured in pounds (lbs) and ounces (oz). It’s important to use the correct unit based on the context of the measurement.
4. Why is understanding mass important in everyday life?
Ans.Understanding mass is crucial because it helps us in various daily activities, such as cooking, where precise measurements are needed for recipes, in science for accurate experiments, and in transportation to ensure that vehicles can carry loads safely.
5. How does mass relate to density and volume?
Ans.Mass is related to density and volume through the formula: Density = Mass/Volume. This means that density is the mass of an object divided by its volume. Understanding this relationship helps in identifying materials and understanding their properties in both scientific and practical applications.
