Is a position time graph and a displacement time graph the same?

Click For Summary
A position-time graph and a displacement-time graph are not the same, as they represent different concepts. Displacement is defined as the change in position and typically starts at zero, while position can begin at any value. In a stationary reference frame, displacement remains constant at zero, but position can vary. The distinction lies in how these terms are used and understood in different contexts. Overall, while they may appear similar under certain conditions, they fundamentally represent different physical quantities.

Displacement could be seen as absolute value.
Displacement probably has to start at zero, while position can start elsewhere.

It will depend on who uses those words in which way.
 
No, they are not. For example, if an object is at rest in the reference frame, the displacement is a constant zero whereas the position can be any constant value.
Displacement represent the change in position so they are different thing, in principle. They may happen to look the same if the original position is the origin of the coordinate system.
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
