Objects with the same mass but different volume have different densities. Summary Students use the water displacement method to find the volume of different rods that all have the same mass. They ...

A planet’s mass and volume are easy to determine. Because planets are nearly spheres, we can calculate volume from our knowledge of a planet’s radius, which we determine by measuring both the ...
