# How does gravity work in water?

Gravity works the same way in water that it works in air or a vacuum -- but you have to consider the force of gravity on the water as well as on the object you put into it.

Gravity can only pull an object through water if an equal volume of water is allowed to resist gravity; this is known as displacement. Essentially, gravity must decide which object to pull down—the submerged one or the water—and buoyancy is essentially forcing gravity to make this decision.

In other words, if the object you are immersing is denser than the water, it will sink, but its apparent weight will be reduced by the volume of water that gets displaced upward; if the water is denser, on the other hand, the immersed object will float up to the point where the displaced volume of water matches the whole object's mass, at which point the net weight will be zero.

Gravity works in water similarly to how it works in air or any other medium. It causes objects to be attracted towards the center of the Earth. When an object is submerged in water, it experiences a buoyant force from the water pushing upwards, counteracting the force of gravity pulling it downwards. The magnitude of the buoyant force depends on the density of the object and the density of the water.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
