FORCE

Force is a physical quantity that can change the state of motion or shape of an object. In the CGS (Centimeter-Gram-Second) system, the unit of force is the dyne, while in the SI (International System of Units), it's the newton.

- CGS unit: 1 dyne = 1 gram * centimeter / second^2

- SI unit: 1 newton = 1 kilogram * meter / second^2

The dimension of force is mass times acceleration (M * L / T^2).

For example, when you push a book across a table, you apply a force to it. This force is what causes the book to move.
