explain the term free fall and state the corresponding kinematical equations of motion in the usual notation |
|
Answer» ong>Answer: Free-falling OBJECT is an object that is falling under the sole influence of gravity. That is to say that any object that is moving and being ACTED upon only be the force of gravity is said to be "in a state of free fall." Such an object will experience a downward acceleration of 9.8 m/s/s. Whether the object is falling downward or rising upward towards its peak, if it is under the sole influence of gravity, then its acceleration value is 9.8 m/s/s. Like any moving object, the motion of an object in free fall can be DESCRIBED by four kinematic equations. The kinematic equations that describe any object's motion are: The symbols in the above equation have a specific meaning: the SYMBOL d stands for the displacement; the symbol t stands for the time; the symbol a stands for the acceleration of the object; the symbol vi stands for the initial velocity value; and the symbol vf stands for the final velocity.

Answer» align="absmiddle" alt="\large\boxed{\rm{\blue{★ムɳรωεя★\leadsto}}}" class="latex-formula" id="TexFormula1" src="https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Crm%7B%5Cblue%7B%E2%98%85%EF%BE%91%C9%B3%E0%B8%A3%CF%89%CE%B5%D1%8F%E2%98%85%5Cleadsto%7D%7D%7D" title="\large\boxed{\rm{\blue{★ムɳรωεя★\leadsto}}}">
Oxygen is a member of group VI A in Mendeleev’s periodic table. Its valency is 2. Similarly, the valencies of all the elements listed can be predicted from their respective groups. This will help in writing the formulae of their oxides. (i) Potassium (K) is a member of group IA. Its valency is 1. Therefore, the formula of it is K2O. (ii) Carbon (C) is a member of group IV A. Its valency is 4. Therefore, the formula of it is C2O4 or CO2. (iii) Aluminium (Al) belongs to groups III A and its valency is 3. The formula of its oxide is Al2O3. (iv) Silicon (Si) is present in group IV A after carbon. Its valency is also 4. The formula oxide is Si2O4 or SiO2. (v) Barium (Ba) belongs to group II A and the valency of the element is 2. The formula of oxide of the element is Ba2O2 or BaO. |
