What force makes an object float on water?

Buoyancy force is what causes things to float in water. To calculate buoyancy, use Archimedes' Principle: the buoyancy force of a submerged (or partially submerged) object is the weight of the volume of water that the object displaces. In other words, find the volume of the object that is under water, and multiply that by the density of water (1000 kg/cubic meter) and gravity (9.8 meter/sec/sec). It is also density that makes things float in water. If the object has less density than water, it will float.

the buoyant force acts in the direction opposite to the force of gravity, so it makes the object feel lighter

It makes it float to the bottom, because of the pressure of the heavy pressure. it makes it float down

Anything will float if the total force of the displacement of water is more than the force of gravity on the object.

In that case, such an object will float.

The DENSITY of the item relative to the density of water determines if it will float or not. If the item is LESS DENSE than water, it will float.

This is archemedies principle. This is a balance between the force on the water displaced by gravity compared to the force on the floating object due to gravity. That is if the average density of the object that whishes to float is less then water then it will float. If it is greater then it will sink. For a boat the average density is the average of the density of the hull and the air inside the hull.

Bouyancy... its what makes things float in water.

Density of the object and buoyancy of the water/liquid.

Gravity Probably I don't know. -Jellyfish

The correct answer is buoyant not put it in water

For an object to float in water it has to be less dense than the water.

If the object does not quite float in water, adding salt to the water might make the object float, yes.

If the density of any material is larger then that of water, the buoyancy force of water will not support that object. ie the object will not float. Also, if an small/large holes are present in the object, they may fill with water to increasing the mass, but not the volume, causing the density to increase. Generally, wood, unless saturated with water, will float. Ebony could be one that doesnt float.

they float because of the upthrust of water (the natural force of water which causes things to float) is greater than the weight of the paper airplane

the salt water is denser because of the salt

it increases the density of the water, making objects float easier. ex. the dead sea.

The floating or sinking of an object depends on the upthrust force the water exerts on the object. By Archmides' principle, Upthrust Force = (Density of Liquid) * (Volume of Liquid Displaced by the object) therefore the upthrust force depends on the density of the liquid, and as salt water has a larger density than fresh water, boats should float better on salt water.

Yes, this is the principle of buoyancy. This is what makes balloons float in the air and boats float on water.

There will be no force created.It is the density of the object to make itself float.Not theupward force which makes the object floats.

Water helps lift an objects via the buoyancy force. The buoyancy force is equal to the weight of water displaced by the volume of the submerged object. If this buoyancy force is equal to the weight of the object, the object will float in that position. If the object is completely submerged and the resulting buoyancy force is less than the weight of the object, it will continue to sink.

The buoyant force always pushes up on an object - if the object weighs more than the water it displaces, the buoyant force will not be sufficient to make it float or be neutrally buoyant.

The object would float in the middle if it was in water.

it`s shape,the shape of an object determine the amount of water or air it displaces which enable buoyancy and the shape will also make an object float through friction reduction also.

The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
