What else can I help you with?
True or false an object buoyant force and weight arent the same thing?
Yes they are different things. Buoyant force is always upward. Weight is always downward. Also ... -- Weight depends on the object's mass. -- Buoyant force depends on its volume, and on what it's floating in.
What is the upward force acting on an object in fluid?
The upward force is what's called the "buoyant force". It's exactly the weight of the fluid that would be in the space occupied by the object if the object were not there. What is the object doing ? Is it sinking ? Then the buoyant force is less than the weight of the object. (A rock.) Is it rising ? Then the buoyant force is greater than the weight of the object. (A basketball forced to the bottom of the pool and then released.) Is it just hanging there ? (typically referred to as "floating") Then the buoyant force is equal to the weight of the object. (A boat.)
Why do things float and some things sink?
Objects float or sink based on their density relative to the fluid they are in. If an object is less dense than the fluid, it will float; if it is more dense, it will sink. This is due to the buoyant force acting on the object, which is the result of the pressure difference between the top and bottom of the object.
What 2 things exert buoyant force?
Two things that exert buoyant force are fluids (such as water or air) and objects submerged in those fluids. Buoyant force is the upward force exerted by a fluid on any object placed in it, which helps objects to float.
What are the 3 things that can cause a change in acceleration?
Three things that can cause a change in acceleration are a change in the net force acting on an object, a change in the object's mass, or a change in the direction of the force acting on the object.

What two things help in determining if an object will float of sink?
You can tell if objects will float or sink byHow buoyant the object isHow dense the object is

What is the reason why some things float or sink because water is what?
Some things float or sink in water due to their density. Objects that are less dense than water will float, while objects that are more dense will sink. This is because the buoyant force acting on an object in water is equal to the weight of the water displaced by the object.
How and why do some things float and others sink?
Objects float when the weight of the water they displace is greater than their own weight, creating an upward buoyant force. Objects sink when their weight is greater than the buoyant force acting on them, causing them to descend in the water. The density and shape of an object determine whether it will float or sink.
if the forces acting on an object are balanced the object may change speed change direction or do both true or false?
If the forces acting on an object are balanced, then the object will do none of those things. The statement is false.
What force stops things from sinking?
Buoyancy is the force that stops things from sinking. It is a upward force exerted by a fluid that opposes the weight of an immersed object. If the buoyant force is greater than the weight of the object, the object will float; if it is less, the object will sink.
How could you determine buoyant force?
Buoyant force can be determined by calculating the weight of the fluid displaced by an object submerged in it. The buoyant force is equal to the weight of the fluid the object displaces, and it acts in the opposite direction to gravity. This force helps objects float in a fluid.
Why do things seem to weigh less in water?
An object has to push the water out of the way (or in other words, displace water) in order to become submerged; the weight of that displaced water creates an opposing force called buoyancy, which pushes the object upward, out of the water.
