What is the downward pull on an object due to gravity called?
Friction. The downward pull of an object due to gravity is known as. weight.
Which is the best prediction Shari could make?
Which is the best prediction Shari could make? Her weight is greater on Venus because Venus has less mass. Her weight is lower on Venus because the acceleration due to gravity is lower.
Is KG a unit of mass or weight?
The SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.
How do you measure the mass of a bag of flour?
Answer. This really depends on how big the bag is. Most commonly, the bag weighs 2 kg to 10 kg or more. With this range of weight, Siobhan should use a balance in order to measure the mass of the flour and record the mass in kilograms.
Which statement summarizes the difference between mass and weight?
Which statement summarizes the difference between mass and weight? Mass is the amount of matter in an object, and weight is the downward pull on an object due to gravity.
What is the difference between mass and weight a mass is the amount of matter in an object and weight is the pull of gravity on an object B weight is the amount of matter in an object and mass is the pull of gravity on an object c mass is always more than weight D weight is always more than?
In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity. Objects on the surface of the Earth have weight, although sometimes the weight is difficult to measure.
Which statement summarizes the difference between a law and a theory?
Which characteristic is least important for her hypothesis to have? Which statement summarizes the difference between a law and a theory? A law describes natural phenomena, but a theory explains why those phenomena occur.
Which example illustrates a chemical change quizlet?
Which example illustrates a chemical change? When hydrogen peroxide bubbles, it is undergoing a chemical change.
What is conserved in physical changes?
Matter is anything that has mass and takes up space. Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
What is conserved in both physical and chemical changes?
The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction or a physical transformation. Hence, a short answer to the question is – yes, mass is conserved whether matter undergoes a chemical change or a physical change.
Can matter be transformed?
It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed.
What is the main difference between physical change and chemical change?
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed.
What is the similarities and differences of physical and chemical properties?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
What does physical and chemical changes have in common?
How are physical and chemical changes similar and different? (compare and contrast) (Physical and chemical changes are similar because matter experiences a change in state, Physical changes are different because matter remains the same substance, just in a different state, whereas chemical changes change the matter …
