Final answer:
The subject of this question is Physics. The shortest time required for an object to move along a fixed distance is called time and the ability to move the body as quickly as possible is represented by the concept of speed.
Step-by-step explanation:
The subject of this question is Physics. In Physics, the shortest time required for an object to move along a fixed distance is called time and the ability to move the body as quickly as possible is represented by the concept of speed.
Speed is defined as the rate at which an object changes its location, and it depends on the time interval of motion.
It is calculated by dividing the distance traveled by the elapsed time of motion.
For example, if an object travels a distance of 100 meters in 10 seconds, the speed would be 10 meters per second.
