MASS AND WEIGHT

Here are the definitions for mass and weight:

• Mass: The mass of a body is the quantity of matter it contains. It is a fundamental property of an object and remains constant regardless of its location. Mass is measured in kilograms (kg).
• Weight: Weight is the force of gravity acting on an object's mass. It is calculated by multiplying the object's mass by the acceleration due to gravity ($W = m \times g$). Weight is a vector quantity and varies depending on the gravitational field. It is measured in Newtons (N).
