What is the difference between weight and mass (in an object)?

• mass is measured with lwh, + weight is measured with water displacement

• mass is the gravity acting on it, weight is the amount of matter

• weight is used for the volume, and mass is used for the density

• weight is gravity acting on it, mass is the amount of matter
