What is the force called pushing up?
The force pushing up is called the normal force. It is exerted upwards by a surface to support an object placed on it and counteract the force of gravity pulling the object downwards.
What is the condition necessary for floatation?
An object will float if the density of the object is less than the density of the fluid it is placed in. This is due to the buoyant force acting on the object, pushing it upwards and balancing the force of gravity pulling it down.
If the buoyant force is less than the weight of an object put in a fluid what will happen to the object?
If the buoyant force is less than the weight of an object placed in a fluid, the object will sink. This is because the force pulling the object down (its weight) is greater than the force pushing it up (buoyant force).
How bodies float on water?
When an object is placed in water, it displaces an amount of water equal to its own weight. If this displaced water weighs more than the object, the object will float. This is because the buoyant force pushing up on the object is greater than the force of gravity pulling it down.
How do weight and upthrust make things float?
When an object is placed in a fluid (like water), it experiences two opposing forces: weight pulling it down and upthrust (also called buoyant force) pushing it up. If the object's weight is less than the upthrust, it will float. This happens because the upthrust force exerted by the fluid is greater than the object's weight, allowing it to stay afloat.

What happens to a positivly charged object is placed within a positive electric field?
A positively charged object placed within a positive electric field will experience a force pushing it in the direction of the field. This force will cause the object to accelerate in the direction of the field lines.
Does an object become heavier when placed in water?
No. It becomes lighter as the water exerts an upthrust on the object according to the archmides' principle. Thus the reaction force ( or the weight ) of an object becomes less.
How is it possible for an object to sink even though a buoyant force is pushing on it?
An object will float if it is less dense than the liquid in which it is placed; if it is denser, it will sink. In terms of forces, if the force of gravity (downward) is greater than the buoyant force (upward), then of course the net force will be downward, and the object will sink.
What happens to items placed in a location in space Do they move, and if so, why or why not?
When items are placed in a location in space, they will remain in that location unless acted upon by an external force. This is because of Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and direction unless acted upon by an external force. So, unless there is a force like gravity or propulsion pushing or pulling the item, it will stay in its current position in space.
What is the role of the normal force on a slope in determining the stability of an object placed on it?
The normal force on a slope helps keep an object stable by counteracting the force of gravity pulling it downhill. The greater the normal force, the more stable the object will be on the slope.
Which liquids and gases exert a buoyant force on objects placed in them?
Liquids such as water and gases such as air exert a buoyant force on objects placed in them. This force is a result of the pressure difference between the top and bottom of the object, pushing it upward.
Why do you object's placed in fluids experience a buoyant force?
Objects placed in fluids experience a buoyant force due to the difference in pressure exerted at different depths in the fluid. This pressure difference results in an upward force on the object, which counteracts the gravitational force pulling it down, causing it to float or rise.
