Which force in fluids described by Archimedes principle allow objects to float?
buoyancy
What force in fluids described by Archimedes'principle allows objects to float?
The buoyant force, according to Archimedes' principle, is what allows objects to float in fluids. This force is equal to the weight of the fluid displaced by the object, pushing it upward and counteracting its weight.
Does hierarchy is a principle of visual design It allows designers to show the viewer which objects are most important?
True
What is the application of force with movement?
The application of force with movement allows objects to accelerate or decelerate depending on the direction of the force applied. This principle is fundamental in mechanics and is described by Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force applied and inversely proportional to its mass.
What is the factor described by Bernoulli's principle that allows airplanes?
Air over the upper surface of the airfoil is induced to move faster than that under its lower surface thus, according to Bernoull's principle, creating a region of lower pressure above the airfoil and a net lift on the airfoil.
Objects that float on water are what in water?
Objects that float on water are less dense than water, which allows them to displace enough water to support their weight and remain on the surface. This is due to the principle of buoyancy, where the upward force exerted by the water is greater than the downward force of the object's weight.
Why is lever used to lift heavy objects?
A lever is used to lift heavy objects because it magnifies the input force applied to it. By using a lever, a person can apply a smaller force over a longer distance to lift a heavier load over a shorter distance. This principle allows for the efficient lifting of heavy objects with less effort.
What is the principle that allows people to predict and control their world?
Causality
What is gestalt principle of closure?
The gestalt principle of closure suggests that our brains tend to fill in missing information to perceive complete and meaningful patterns. This allows us to mentally complete shapes or objects that are not fully present based on surrounding elements, helping us make sense of fragmented visual stimuli.
What principle explains why lifting heavy objects is easier using ramps?
Using a ramp to lift heavy objects makes it easier because it allows the force required to move the object to be exerted over a longer distance, reducing the amount of force needed at any one point. This principle is known as mechanical advantage - by increasing the distance over which the force is applied, less force is needed to do the same amount of work.
How do you describe scientifically what you see happening when objects move?
When objects move, their position changes with respect to time, which can be described using concepts such as velocity and acceleration. These changes in position are governed by the laws of physics, specifically Newton's laws of motion, which explain how objects interact with forces to produce motion. Observing the motion of objects allows scientists to analyze and predict their behavior based on mathematical models and principles of motion.
Why is Archimedes' principle important?
Archimedes contributed the theory of buoyancy, which is significant because it allows us to measure an object's weight by its displacement in water, density, displacement, and the buoyancy of the liquid in which the object is acting.
