Newton’s first law of motion states that “A body at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it”. Suppose a block is kept on the floor, it will remain at rest until we apply some external force to it. Also, we know that it takes us more effort or force to move a heavy mass. This is directly related to the property known as Inertia. Hence, the first law of motion is also known as the law of inertia.
The second law of motion describes what happens to the massive body when acted upon by an external force. The law states that the force acting on the body is equal to the product of its mass and acceleration.
The third law of motion describes what happens to the body when it exerts a force on another body. The law states that when two bodies interact, they apply force on each other that are equal in magnitude and opposite in direction. A force resting on a table applies a downward force equal to its weight on the table.

Physical Properties of Bases
- Bases taste bitter – There are very few food materials that are alkaline. It is even more important that care be taken in tasting bases. Tasting of bases is more dangerous than tasting acids because of the property of stronger bases to denturate protein.
- Bases release a hydroxide ion in water solution.
- Bases neutralise acids in a neutralization reaction – The word reaction means that an acid plus a base makes water plus a salt. Symbolically where “Y” is the anion of acid “HY”. ‘X’ is the cation of base ‘XOH’ and ‘XY” is the salt in the product, the reaction is
HY + XOH → HOH + XY
- Bases denature protein – This accounts for the slippery feeling on the hands when exposed to a base. Strong bases that dissolve in water well, such as sodium or potassium lye, are very dangerous because a great amount of the structural material of human beings is made of protein. Serious damage to flesh can be avoided by careful use of strong bases.
- Bases turn red litmus to blue – This is not to say that litmus is the only acid base indicator, but that it is likely the oldest one.
