Measuring the Effect of Upthrust in Water

In Tamar Class we have been learning about forces. We discovered that upthrust is a pushing force which makes objects in water have less weight. When the force of upthrust is larger than the force of gravity, objects float. We used Newton meters to weigh objects in the air and in water and we found that objects weigh less in water whilst their mass stays the same.
