It is caused by the difference in density between wood and water.
One cubic foot of wood is usually lighter than one cubic foot of water, hence the water goes up a little but the wood goes up more.
The overall density of the wood block is less than that of the water, so it floats.
The basic principle is that when a solid object is immersed in a fluid, the solid displaces some of the fluid. This causes an upthrust on the solid, equal to the weight of fluid displaced. If the upthrust is equal to the weight of the solid it floats.
The buoyant force exerted by the water on the block of wood keeps it floating. The weight of the wood is less than the weight of the water it displaces, allowing it to stay afloat. The block of wood will sink if its weight exceeds the buoyant force acting on it.

What is the apparent weight of the floating block when a block of wood is floating in a lake?
The apparent weight of the floating block is equal to the weight of the displaced water, according to Archimedes' principle. Since the block is floating, its weight is balanced by the upthrust force of the water pushing up on it. So, the apparent weight of the floating block is less than its actual weight.
Giving reasons state the reading on a spring balance when it is attached to a floating block of wood which weighs 50g in air?
The spring balance will read zero when attached to a floating block of wood. This is because the block of wood is buoyed up by the water, leading to a net force of zero acting on the block in a state of equilibrium.
What is the buoyant force on a 30 lb block of wood floating in a lake?
The buoyant force on the block of wood is equal to the weight of the water displaced by the block, which is 30 lb. This is because the block is in equilibrium, with its weight equal to the buoyant force pushing it up.
What is wood floating in water called?
Wood floating in water is called driftwood. Driftwood is wood that has been washed up onto a beach or shore by the action of tides, waves, or wind.
Which force keeps a piece of wood floating?
The force of buoyancy, which is the upward force exerted by a fluid on an object immersed in it, keeps a piece of wood floating. This force is equal to the weight of the fluid displaced by the object, allowing the wood to stay afloat as long as its weight is less than the weight of the fluid it displaces.
A block of wood is floating in water The weight of the part of the block above water is one-third of the block What is the weight of the water displace by the block of wood?
The weight of water displaced by the floating block of wood is exactly equal to the weight of the ENTIRE block of wood, regardless of how much of the wood is above the water level.

How do you move a block of wood without touching it?
Is the block of wood floating in water? If so, then a drop of dishwashing soap dropped into the water next to the wood, will cause the wood to float away from the drop of soap. The effect is quite pronounced on small pieces of wood, and it is positively dramatic on tiny things like parsley flakes floating on the water. What's happening is that the piece of wood floating in the water is acted on by the surface tension of the water. The water pulls in every direction, so the wood doesn't move. A tiny drop of soap will break the surface tension of the water, and the surface tension on all the OTHER areas of water will cause the wood to be pulled away from the soap drop.
What is the buoyant force on a 30 lb block of wood floating in a lake?
The buoyant force on the block of wood is equal to the weight of the water displaced by the block, which is 30 lb. This is because the block is in equilibrium, with its weight equal to the buoyant force pushing it up.

Which will float on the water 1 kg block of wood or 1 g block of aluminum?
wood
Which force keeps a piece of wood floating?
The force of buoyancy, which is the upward force exerted by a fluid on an object immersed in it, keeps a piece of wood floating. This force is equal to the weight of the fluid displaced by the object, allowing the wood to stay afloat as long as its weight is less than the weight of the fluid it displaces.
How does the mass of a floating wood compare to the mass of water displaced?
equal
Does a block of wood sink in water?
Yes, a block of wood will typically float in water because wood is less dense than water. This means that the weight of the water displaced by the block of wood is greater than the weight of the wood itself, causing it to float.
Will a block of wood with a mass of 1000 grams will sink in water?
No. It doesn't matter how heavy a block of wood is, it depends on the density of the wood. Generally wood floats as the density of wood is lighter than the density of the water, so it would float.
Which will float on water a 1-kg block of wood or a 1-kg block of aluminum?
The 1-kg block of wood will float on water, while the 1-kg block of aluminum will sink. This is because wood is less dense than water and has a greater buoyant force acting on it, causing it to float. Aluminum is denser than water and will sink when placed in water.
