| > Which is heavier 2kg of bread or 1kg of copper?
|
| The weight of an object depends on two factors - its mass and the acceleration due to gravity. Since we are comparing weights at Earth's surface, where the acceleration due to gravity is constant (approximately 9.8 m/s²), we can simply compare their masses. Copper has a higher density than bread, meaning that 1 kg of copper occupies less volume than 2 kg of bread. Therefore, 1 kg of copper is heavier than 2 kg of bread.
