What happens when the forces upthrust and air resistance are applied to objects?

If enough upthrust is added to an object then it will be pushed upwards. If enough air resistance is applied to an object then it will move in the direction which the air resistance is pushing it in. If you are already falling, then you will have air resistance. If it is increased when you open a parachute for instance, then you will slow down.

Can upthrust be greater than weight?
YES...and examples are flying objects! Interestingly,Any liquid or gas produces upthrust. For example, the upthrust of air keeps a hot air balloon up.
The force that acts on objects immersed in or floating on a liquid?
Upthrust from the liquid.
How do you find an objects acceleration from its mass and the force acting on it?
Acceleration= total force / mass. Total force might be applied force minus frictional force, or applied force minus air resistance etc.
Do falling objects have air resistance?
Yes falling objects do have air resistance. They have even more if they have a larger surface area.
how do objects fall when there is no air resistance?
In the absence of air resistance (friction) objects will fall at the same speed. Hope this still helps :)

What objects use upthrust?
many things use upthrust, some i can name are: a hot-air-balloon, a aeroplane a parachute and possibly a elevator.
What is the force that pulls objects up in the water?
Objects in water or other fluids can be pushed up to the surface by buoyancy.
What is up thrust?
upthrust is a force which helps objects on water or in air to not drop or sink
What is upthurst?
This is the name given to a bouyancey force. When an object diplaces a fluid, the amount of upthrust received is proportional to the volume of fluid displaced. When an object is floating then the upthrust is equal to the objects weight. When more people get on to a boat, the boat sinks further into the water, displacing more water so that the upthrust increases to balance the new weight. If an object sinks then the amount of upthrust it receives is less than the weight so the object falls. Just because it sinks doesn't mean that there is no upthrust, there is. This is why heavy objects appear lighter if you place them in water.

How do objects react when a force is applied?
Objects acccelerate when a force is applied, a=F/m.
What happens to the body when the upthrust is less than the weight of the object'?
An object that is COMPLETELY submerged in water has its Upthrust equal its weight, but it doesn't necessarily float, an object could be at the rock-bottom of the ocean, and it would still have its upthrust equal to its weight. This is because the upthrust is equal to the weight of the fluid displaced, and so while the objects volume remains constant, and assuming the density of the fluid it displaces is constant.. The upthrust remains constant, this is unless the object compresses and has its density altered.. I know I didn't directly answer your question, but I hope this helps.. Even if a little.
What are the 4 types of force and their definition?
there are 5 main types friction...try to slow things down gravity...any two objects have gravity of attraction between them static electricity...can attract charged things magnetism...attract objects made from iron upthrust...pushes things fluid(liquid and gases) air resistance and water resistance type of friction. there are also two forces called pressure force and moments force.
Does depth affect water resistance?
Resistance of water is probably defined as pressure being applied by water on objects and as it's stated in fluid mechanics books pressure increases as height decreases or depth increases, so simply the answer is "yes".
Do falling objects have air resistance?
Yes falling objects do have air resistance. They have even more if they have a larger surface area.
