# Finding the Appropriate Graph

## WHat is an appropriate GrAPH?

### This has been touched upon in N5 Physics through the Gas Law Graphs relating to temperature. ### However, by converting the data to Kelvin by adding 273 to the temperature data, it can be seen that the data does then follow a directly proportional relationship, and therefore passes through the origin.  ## Example 1

### Use the formula below to investigate how the Voltage across a set of parallel plates affects the Velocity of a charged particle. ### If this formula is correct, by rearranging this formula to the y = mx + c format will give a straight line through the origin.   ## Example 2

### Use the formula below to investigate how the distance between two objects affects the Gravitational Force between them. ### If this formula is correct, by rearranging this formula to the y = mx + c format will give a straight line through the origin.  ## Example 3

### Use the formula below to investigate how the semi-major axis of an orbit affects the Period of that orbit. ### If this formula is correct, by rearranging this formula to the y = mx + c format will give a straight line through the origin.
