Final answer:
The change in position divided by the change in time defines average velocity, while the rate of change of velocity is known as acceleration.
Step-by-step explanation:
The change in position divided by the change in time is known as average velocity. Average velocity is a vector quantity that refers to the displacement over the time during which that displacement occurs. This should not be confused with average speed, which is the total distance traveled divided by the time of travel, regardless of direction.
When we talk about the rate of change of velocity, this is referred to as acceleration. Acceleration is a vector quantity and can be calculated as the change in velocity divided by the time over which the change occurs. In physics, the correct formula to determine acceleration is change in velocity (Δv) divided by the change in time (Δt).
The change in position divided by the change in time is called velocity. Velocity measures the rate at which an object changes its position, taking into account both the magnitude and direction of motion.
