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.
When an object floats the forces of weight and the force of upthrust are?
They must be equal. We know that, because if the vertical forces on the object didn't add up to zero, then it would be accelerating vertically, either up or down.
What are the action and reaction forces on the fabric of a parachute when it is deployed?
When a parachute is deployed, the action force is the air resistance pushing against the parachute fabric. This air resistance is created by the change in the air's velocity as it passes through the canopy of the open parachute. The reaction force to this action force is the drag force created by the parachute pulling against the jumper. This drag force is created by the increase in the parachute's surface area, which slows the jumper down as they fall. The drag force is also responsible for the parachute's ability to slow the jumper's descent enough to safely reach the ground.
What force makes a straw and clay ball float even though there is a force pulling them down?
upthrust
What are the two forces that act on a stationary boat that is afloat?
The two forces that act are the weight of the boat (mass times gravity) and the upthrust of the water. If the boat is in equilibrium on the water (e.g. not sinking) then upthrust will equal weight

The force which slows down a parachutist?
Air resistance or upthrust :)

What is the reason for upthrust?
There are several answering services that also have this question or similar ones on it. From answerbag.com, the question asked was: what is upthrust? The answers were: * Upthrust is the upward force exerted on an object in a fluid. It arises as a result of the difference in pressure exerted by the fluid on the surface of the object at different depth. * Up thrust is the force that pushes objects up and makes them seem to loose weight in a fluid (note - a fluid means a liquid or gas) When you are standing on the ground gravity keeps you down but upthrust stops you from falling into the earths core. In a way upthrust makes things hard!! Because if it didn't exist solids wouldn't be solid.An objects density effects how it floats. * Density = Mass * ------- * Volume * Upthrust is also called buoyancy. It is the upward force produced on an object in a fluid (such as air or water). The force is equal to the weight of the fluid displaced by the object. If that weight is greater than the weight of the object, the object will float in the fluid. If it is equal, it will sit suspended. If it is less, it will sink, but the object will weigh less than it would in a vacuum. Hence, it is easier to pick up a heavy object in water than in air - the amount of displaced water weighs more than the equivalent volume of air, therefore water produces a greater upthrust. In wiki answers the question asked was: = What does upthrust mean? = The answer was: Upthrust is a type of force that pushes upwards

Which forces slow things down out of upthrust friction weight and air resistance?
Air resistance and friction. Weight can sometimes slow you down if your going up in like a plane or rocket. UpTHRUST THRUST=Push
What makes a person slow down when their parachute opens?
force
What is the name of the force which slows down a man falling with a parachute?
air resistance , maybe!
What force slows things down?
Friction, when moving sideways. Upthrust when you are trying to go down. gravity when you are trying to go up
What causes a parachute to slow down?
A parachute... •_•
