7. Slow or fast

 

 

Being ahead of another object does not necessarily mean that the object is moving fastermeans farthest object is always slowermeas position and speed are the samealways means greater speed. To decide which object is faster, we need to compare the position at a particular instantdistance covered in a given amount of timetime taken without distancedistance covered without time. For example, one child may be farther ahead because they started earlierwas smaller in sizestopped earlierstarted later or have already covered more distance. The other child may still be moving slowermoving fasterbeing farther from the finish lineremaining stationary if they cover a greater distance during the same time interval. Therefore, only directiononly distanceboth distance and time must be consideredonly time when comparing the speed of objects. Hence, the speed and position are identicaltime is unnecessaryposition of an object alone cannot be usedposition alone determines speed to decide whether it is moving fast or slow.
