Motion In A Straight Line
##Concepts to remember for Motion in a Straight Line:
| Concept | Definition |
|---|---|
| Frame of reference | A coordinate system used to describe the motion of an object |
| Position | The location of an object in space relative to a frame of reference |
| Displacement | The change in position of an object |
| Distance | The total length of the path traveled by an object |
| Speed | The rate at which an object changes its position |
| Velocity | The rate at which an object changes its position in a specific direction |
| Uniform motion | Motion in which an object travels the same distance in equal intervals of time |
| Non-uniform motion | Motion in which an object travels different distances in equal intervals of time |
| Acceleration | The rate at which an object’s velocity changes |
| Uniform acceleration | Acceleration in which an object’s velocity changes by the same amount in equal intervals of time |
| Non-uniform acceleration | Acceleration in which an object’s velocity changes by different amounts in equal intervals of time |
