What are the similarities and differences between kinetic and potential energy?
What are the similarities and differences between kinetic and potential energy? KE is the energy possessed by an object by virtue of it being in motion. PE is the energy possessed by an object by virtue of its position. It can be transferred from one object to another and this happens during collisions. Potential Energy, […]
Why does losing gaining an electron cause the other element to gain lose atoms?
Why does losing gaining an electron cause the other element to gain lose atoms? Answer: A positive ion is formed where an atom has more protons than electrons. Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to […]
What is the actual weight of molecule of water?
What is the actual weight of molecule of water? Therefore, 18g of mass of water is occupied by 6.022×1023 number of molecules. Therefore, we can calculate the mass of one molecule of water by dividing the mass of one mole of water and Avogadro number. The actual weight of a molecule of water is calculated […]
How gravity affects the movement of object?
How gravity affects the movement of object? On Earth, gravity pulls all objects to Earth’s center. Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the […]
What is the difference between momentum and velocity?
What is the difference between momentum and velocity? As nouns the difference between velocity and momentum is that velocity is (physics) a vector quantity that denotes the rate of change of position with respect to time, or a speed with the directional component while momentum is (physics) (of a body in motion) the product of […]
