Displacement
Displacement measures how far we are from our starting position.
Importantly, we measure it in a certain direction, so it’s a vector quantity.
Example
Section titled “Example”- Let’s suppose we walk 1km north, then 2km back.
- THe total distance we travelled is 3km.
- But our displacement is 1km south: because that’s how much our current position has changed.
Where:
is the displacement, measured in metres, is the velocity, measured in metres per second, ( ) is the time, measured in seconds,
