Is it true that two objects that have the same volume will always have the same weight?
no ,its not necessary tht two objects have same volume have the same mass because the density of the material they are made up of can be different. Therefore, the objects can have different densities. However, if two objects have the same mass andvolume, they will have the same density.
Does Matter always have weight?
All matter has mass and occupies space. Volume is a measure of how much space an object occupies. “Mass” only depends on how much matter is in an object. “Weight”, on the other hand, depends on how strongly gravity pulls on an object.
What is two or more pieces of matter that can be combined but Cannot be easily separated?
How are compounds different from mixtures? The atoms in compounds are combined in fixed proportions and cannot be separated by physical means. A mixture is made of two or more substances that can be easily separated by physical means.
What is something that can be observed measured or described when looking at a piece of matter?
physical property. something that can be observed, measured, or described when looking at a piece of matter. States of Matter.
What is difference between mass and volume?
Volume – How much space an object or substance takes up. Mass – Measurement of the amount of matter in an object or substance.
What do we measure mass with?
triple beam balance
How mass is calculated?
The mass can be calculated by dividing the net force acting on an object by the acceleration of the object. When talking about net force, we use the units kilogram meter per second squared. This is also known as a Newton. The units for acceleration is meters per seconds squared, and the units for mass are kilograms.
Does mass depend on weight?
Mass is independent of gravity and is therefore different from weight. See Note at weight. An object’s weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.
What happens to your weight when your mass increases?
As your body grows, you will have more mass, which also means you will weigh more. That’s because when you’re on the earth, the amount of gravity that pulls on you stays the same. So when your mass changes, so does your weight!
Do heavier objects fall faster?
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance.
Why does weight change but not mass?
While the weight of an object varies in proportion to the strength of the gravitational field, its mass is constant, as long as no energy or matter is added to the object. For example, although a satellite in orbit (essentially a free-fall) is “weightless”, it still retains its mass and inertia.
Why does the mass remain constant?
Answer. Mass independent upon gravity but weight is depend upon gravity. So, we can say that the mass of an object remains constant at all places but weight do not constant it changes due to changing of places….
What conditions must be met for an object to be weightless?
when the space shuttle orbits the earth, the shuttle and all the objects in it are in free fall. they are falling in a curved path around the earth, instead of straight downward. as a result, objects in the shuttle appear to be weightless. a falling object is in free fall if the only force acting on it is gravity.
Is it possible for your weight to change as your mass remains constant?
Is it possible for your weight to change while your mass remains constant? Yes, weight is determined by gravity. Therefore, on the moon you would be a different weight but your mass would be the same.
Will all the objects have same weight irrespective of the place explain?
The weight of an object will change if the object is brought farther away from Earth, or placed on a different planet, since the force of gravity on the object will change. However the mass of the object will remain the same regardless of whether the object is on Earth, in outer space, or on the Moon.
Does weight change with location?
A person can weigh differently at various place on Earth because of the fluctuations in Earth’s gravity, according to a new high-resolution map. Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense, researchers said.
Is there any way that an object’s mass changes?
The mass of an object does not change with speed; it changes only if we cut off or add a piece to the object. Force = mass × acceleration (Newton’s Second Law); this is, to accelerate something, you need only apply a net force to it.
Is mass really constant?
Conserved? Mass is both a property of a physical body and a measure of its resistance to acceleration (rate of change of velocity with respect to time) when a net force is applied. An object’s mass also determines the strength of its gravitational attraction to other bodies.
Does mass change size changes?
Changing the shape does not change its mass or volume, so density remains the same.
Why is mass infinite at the speed of light?
The energy of a particle diverges to infinity as it approaches the speed of light. Since we can never have infinite energy for a particle, the speed of light cannot be reached. Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well.
Does mass affect speed?
Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.
What does M mc2 mean?
“Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa.
How did Einstein prove E mc2?
September 27, 1905. In the fourth paper, Einstein explained the relationship between energy and mass. That is, E=mc2. In other words, energy = mass x the speed of light squared. In their interiors, atoms (mass) fuse together, creating the tremendous energy of the sun as described by Einstein’s famous equation.
What is E mc2 called?
E = mc2, equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other.
Why is speed of light squared?
The reason is that energy, be it light waves or radiation, travels at the speed of light. But why is the speed of light squared? The reason is that kinetic energy, or the energy of motion, is proportional to mass. When you accelerate an object, the kinetic energy increases to the tune of the speed squared.
Why is E mc2 wrong?
Einstein’s second mistake with his equation was in his failure to realize that the primary meaning of E=MC2is that it defines the mass of the photon as the truest measure of mass. If Einstein would have allowed the photon its fair share of the mass, then there would be no case where mass is converted into energy.
