An object underwater feels lighter than it does in aor because of buoyancy.

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

Objects are lighter in water than in air because water exerts an upward buoyant force on objects, counteracting the downward force of gravity. This buoyant force reduces the effective weight of the object in water, making it feel lighter. Objects that are less dense than water will float, while those that are denser will sink.

Are objects lighter in water than in air?

Yes, objects are generally lighter in water than in air due to the buoyant force exerted by the water. This force opposes the gravitational force on the object, making it feel lighter in water.

Do objects weigh more in the air or in water?

Objects weigh less in water than in the air because water exerts an upward buoyant force on the object, partially offsetting its weight. This is known as buoyancy, which makes objects feel lighter in water than in air.

Why can you lift heavy objects in water easily than to air?

You can lift heavy objects more easily in water than in air because water provides more buoyant force than air due to its higher density. This buoyant force counteracts the weight of the object, making it feel lighter in water.

Do objects weigh less in water or do they just appear to be weightless?

Objects weigh less in water than they do in air because of the buoyant force exerted by the water. This force counteracts the weight of the object, making it feel lighter or even weightless when submerged in water.

Will helium float in water?

Yes, helium will float in water. Helium is lighter than air, so it will also be lighter than water and rise to the surface when submerged in water.

What is the direction of acceleration for an object in the air?

Heavier than air objects accelerate downwards. Lighter than air objects accelerate upwards until they are no lighter than the air around them.

Do plastic float on water?

depends if the plastic is heavier or lighter than water and if its hold air which is lighter than water

Why does a helium balloon go up?

A helium balloon goes up because helium is lighter than the surrounding air, creating a buoyant force that lifts the balloon. This is due to the lower density of helium gas compared to the denser air around it, causing the balloon to float upwards.

Do objects weigh less in water or do they just appear to be weightless?

Objects weigh less in water than they do in air because of the buoyant force exerted by the water. This force counteracts the weight of the object, making it feel lighter or even weightless when submerged in water.

Will helium float in water?

Yes, helium will float in water. Helium is lighter than air, so it will also be lighter than water and rise to the surface when submerged in water.

Does lighter objects fall down faster then heavier objects?

No, in a vacuum, all objects fall at the same rate regardless of their weight. This is known as the principle of equivalence. However, in the presence of air resistance, lighter objects may experience less air resistance than heavier objects, giving the illusion that they fall faster.

Why is there an upward force on objects water?

The upward force on objects in water is due to buoyancy. When an object is submerged in water, the water exerts an upward force on the object that is equal to the weight of the water displaced by the object. This helps support the object's weight, making it feel lighter in water.

Which body moves faster heavier or lighter?

In a vacuum, all objects fall at the same rate regardless of their weight due to gravity. However, in real-world conditions with air resistance, lighter objects tend to fall slower than heavier objects because air resistance affects lighter objects more.
