Instantaneous Speed (AQA GCSE Physics): Flashcards

Speed of an object at a particular instant/exact moment in time

Exact moment, not entire journey or time interval

Instantaneous speed at that exact moment

Measure how fast wheels turn at exact moment

Speed of vehicles at a particular instant

Sensors and GPS devices

Using distance travelled in very short time period: $speed = \frac{distance}{time}$

$speed = \frac{distance}{time}$

When instantaneous speed has same value throughout journey

Does not change
