What are the forces on the plasticine when it is floating?
Gravity and Upward force. If the upward force is greater than the weight caused by gravity than the plasticine will float.
What are ways that will make a plasticine float on water?
put in in water
Does a plasticine ball float on water?
no
Does plasticine block a funnel of water from going in to the bottle?
Yes
WHY do heavier odjects sink on water?
An objects weight has nothing to do with sinking or floating (ships are very heavy).If an object is less dense than the equivalent volume of water, it will float.If an object is more dense than the equivalent volume of water, it will sink.If an object is exactly as dense as the equivalent volume of water (at its displacement depth), it will exist in perfect equilibrium, neither sinking nor floating.

What does mean that plasticine has higher density value that water?
means that plasticine has higher density.
What physical property is demonstrated by a piece of styrofoam floating on water?
There are several. They would include displacement, buoyancy, and density.
Why does displacement matter for floating or sinking?
The weight of the water (or other liquid, or gas) displaced is equal to the force with which the water will push the object upwards.
What does it mean when displacement is talked about in sailboats?
Simply put, the displacement of any boat is the amount of water the hull displaces when it floats. The weight of the water being displaced will be equal to the weight of the boat...assuming it's still floating, that is.
What happens when the water around objects have a force greater than the object's weight?
The water around floating object's is a measure of that object's "Displacement". For the object to float the weight of displacement must equal the object's weight. If the water around an object is of a greater weight than an object's displacement, then the object will sink.

How can hardened plasticine be made soft?
Add water drops this will make it
How would you find the density of plasticine?
Roll the plasticine into a sphere and measure the diameter and use the formula for the volume of a sphere V=pi r^2, then weight the sphere to get the mass and use Density = Volume upon Mass. Alternatively, use Archimedes' principle: 1) Weigh a piece of plasticine to get its mass. Very carefully fill a glass with water so full that it cannot contain one more drop of water. Immerse the plasticine in the glass, collecting the water that has run out of the full glass. The volume of the water is equal to the volume of the plasticine. Determine the volume of the water by either weighing it (density of pure water is 1 g per mL) or by accurately measuring the volume. Density = mass (g)/ volume (mL) 2) If you have a balance that can determine mass of an hanging object, first weigh your plasticine to determine its mass. Then attach it to string and take its mass hanging (the string also has mass). Then take its mass while the plasticine is just submersed in water. It will weigh less when submersed in water. The loss of mass when submersed is equal to the mass of water that has the same volume as the plasticine. (density of water is 1 g per mL) Now you can determine the volume of the plasticine since the mass lost in g equals the volume of water in mL. Density is the original mass divided by the volume.
What is a water displacement?
Water displacement is when you put something in water and it gets displaced By Anne
