Final answer:
The instantaneous velocity of a toy car is not the same as its average velocity on a closed interval. Instantaneous velocity refers to the velocity at a specific instant in time or over an infinitesimally small time interval, while average velocity is calculated over a finite time interval.
Step-by-step explanation:
The instantaneous velocity of a toy car is not the same as the average velocity of the toy car on a closed interval. Instantaneous velocity refers to the velocity at a specific instant in time or over an infinitesimally small time interval. On the other hand, average velocity is calculated over a finite time interval.
For example, if a toy car is moving along a track, its instantaneous velocity at a particular moment might be 2 m/s. However, if we calculate the average velocity over a 10-second interval, it might be 1.5 m/s.
So, while instantaneous velocity represents the velocity at a precise moment, average velocity gives us an overall measure of speed over a longer time period.
