Difference between Mass and Weight

I. Mass 

A. Definition of mass: 

Mass is a fundamental property of matter that measures the amount of matter in an object. 

B. Units of mass: 

The units of mass include kilograms (kg), grams (g), pounds (lbs), and ounces (oz). 

C. Properties of mass: 

Mass is a scalar quantity that does not change unless matter is added or removed from the object. It is an intrinsic property of an object that does not depend on external factors. 

D. Physical quantity: 

Mass is a fundamental physical quantity, along with length and time, that can be measured and quantified. 

E. The effect on gravity: 

Mass has a direct effect on the force of gravity between two objects. The greater the mass of an object, the stronger the force of gravity it exerts on other objects. 

F. Measuring Techniques: 

Mass can be measured using a balance or a scale. A balance compares the mass of an object to a known mass, while a scale measures the force of gravity acting on an object. 

G. Formula & SI Unit: 

The formula for mass is m = F/a, where m is the mass, F is the force, and a is the acceleration. The SI unit for mass is the kilogram (kg). 

H. Examples of mass in daily life: 

Examples of mass in daily life include the mass of a person, the mass of a car, or the mass of a book. 

II. Weight 

A. Definition of weight: 

Weight is the force exerted on an object due to gravity. 

B. Units of weight: 

The units of weight include newtons (N), pounds (lbs), and kilograms (kg). 

C. Properties of weight: 

Weight is a vector quantity that depends on the mass of an object and the acceleration due to gravity. 

D. Physical quantity: 

Weight is a physical quantity that can be measured and quantified. 

E. The effect of gravity: 

The weight of an object is directly proportional to the acceleration due to gravity. The greater the gravitational force on an object, the greater its weight. 

F. Measuring Techniques: 

Weight can be measured using a scale or a balance. A scale measures the force of gravity acting on an object, while a balance compares the weight of an object to a known weight. 

G. Formula & SI Unit: 

The formula for weight is W = m x g, where W is the weight, m is the mass, and g is the acceleration due to gravity. The SI Unit of weight is Newton (N).

H. Examples of weight in daily life: 

Examples of weight in daily life include the weight of a person, the weight of a car, or the weight of a book.
