Difference Between Mass and Weight Class 9
What is Mass?
Mass refers to the amount of matter present in an object. It is a physical property of an object and is usually measured in kilograms. Mass does not depend on gravity and remains the same regardless of the location of the object. It is an intrinsic property of matter and cannot be created or destroyed. For example, the mass of a book on the earth will remain the same if taken to the moon.
What is Weight?
Weight refers to the force exerted by gravity on an object. It is dependent on the mass of the object and the acceleration due to gravity. Weight is usually measured in newtons. The weight of an object changes with the location and gravitational force acting on it. For example, if a book weighs 10 newtons on earth, then it will weigh only 1.67 newtons on the moon due to the moon’s lower gravitational force.
Relationship between Mass and Weight
Mass and weight are related to each other through the formula W=mg, where W is the weight, m is the mass of the object, and g is the acceleration due to gravity. This formula governs the weight of an object on the earth’s surface, where g is approximately 9.8m/s². Weight is a vector quantity as it has both magnitude and direction, whereas mass is a scalar quantity.
Conclusion
To summarize, mass and weight are two different physical properties of an object. Mass refers to the amount of matter present in an object, whereas weight refers to the force exerted by gravity on an object. Mass remains constant regardless of the location of the object, whereas weight changes with the location and gravitational force acting on an object. It is important to understand the difference between mass and weight to make accurate calculations in the field of science and engineering.
Table difference between mass and weight class 9
Sorry, as an AI language model, I cannot create a table with HTML coding. However, I can provide you with the difference between mass and weight in class 9.
Difference between Mass and Weight:
Mass and weight are two fundamental and basic concepts in physics. Mass is the amount of matter in an object, whereas weight is the force of gravity acting on an object’s mass. The fundamental difference between mass and weight is that mass is a scalar quantity, whereas weight is a vector quantity.
Mass Weight
Mass is the total amount of matter in a body. Weight is the force of gravity acting on an object’s mass.
It is a scalar quantity. It is a vector quantity.
The SI unit of mass is kilogram (kg). The SI unit of weight is Newton (N).
Mass remains constant everywhere. Weight varies from place to place.
The formula used to calculate mass is m = ρV. The formula used to calculate weight is W = mg.
In simple words, we can say that mass is an intrinsic characteristic of an object that remains constant, whereas the weight of an object can fluctuate based on the gravitational pull of different planets, stars, or celestial bodies.
