International System of (SI) unit has been adopted for measurement by
scientists all over the world. |

|
Three fundamental units needed in physics are those of lengths, mass and time. |
| |
|
Units of all other physical quantities we come across in physics are derived from these fundamental units. |
| |
|
Least count of an instrument is the smallest reading that you can measure accurately with that instrument. |

|
mks
units of length, mass and time are meter, kilogram and second. |
| |
|
The time period of a simple pendulum depends upon its length and acceleration due to gravity. |
