No, being heavier does not necessarily mean an object is more dense. Density is determined by both the mass and the volume of an object. While heavier objects tend to have more mass, they may also be larger in volume, which could result in a lower density compared to lighter objects.

Density = Mass/Volume

- Mass refers to the amount of matter an object contains. It is often measured in kilograms (kg).

- Volume refers to the amount of space an object occupies. It is often measured in cubic meters (m^3).

An object with a high density has a relatively large mass compared to its volume, while an object with a low density has a relatively small mass compared to its volume.

Examples:

- A bowling ball is denser than a basketball, even though the basketball is heavier. This is because the bowling ball has a smaller volume than the basketball.

- A block of wood is less dense than a block of metal, even though the block of metal is lighter. This is because the block of wood has a larger volume than the block of metal.
