Sub Topic Name : Why Objects Float Or Sink When Placed On The Surface Of Water |
Whether an object will float or sink depends on its density relative to the density of the fluid it is immersed in.
Gravity, Buoyancy, Pressure exerted by Fluids
Experiment with different objects and see whether they float or not. First predict what will happen and then test it out.
A blade floats while a pin sinks. Though both have same mass and density. How is that possible?
Key Words | Definitions (pref. in our own words) |
---|---|
Buoyant Force/ Up thrust | Upward force exerted by water on an object |
Density | Mass per unit volume |
Gadgets | How it can be used |
---|---|
Applet | Explain with animations – objects tht float and that don’t |
Boats and Ships, submarines
Shipping Industry
Examples | Explainations |
---|---|
Ships, Boats | This entire use of water as a transport system is soly on the fact is that ships/boats float |
Some objects float and some don’t. Depends on density.
