In physics, mass is the measure of how much matter there is in a particular object or system. Weight, on the other hand, refers to the gravitational force exerted by an object on something else.

Mass and weight are two different concepts that refer to the same thing. They are not interchangeable and should not be used interchangeably to describe an object’s weight. For example, if you weighed yourself before and after eating, you would see your mass increase. Your weight would not change because your mass increased by eating more food.

Weight: The weight of an object is the gravitational force exerted on the object by Earth.

weight = mass x acceleration also

weight = mass x gravity

Example:

This formula calculates the weight of a car by taking its mass and multiplying it by the car’s acceleration.

weight = mass x acceleration

weight = 5000kg x 9.8m/s^2

weight = 49000kg

Mass: Mass is a measurement of the amount of matter in an object.

Mass = weight * (length of the object in meters)

Example:

Mass of a 5 kg rock = weight * (length of the rock in meters)

Mass of the rock = 5 kg * (120 cm)

Mass of the rock = 0.4 kg
