The correct answer is: Option (B) Velocity is how fast an object moves and acceleration is the rate of change in velocity.
Explanation:
The formula for the velocity is given as:
velocity = displacement/time;
It tells us how fast an object cover the distance between two points. In other words, we can say that how fast an object moves in unit time.
Acceleration, on the other hand, is defined as:
Acceleration = change-in-velocity/time
In Physics, we use the term "rate" of a certain quantity changes with time. Here that "certain quantity" is "change-in-velocity." Therefore, acceleration is said to be the rate of change in velocity.
Hence, the correct answer is option (B) Velocity is how fast an object moves and acceleration is the rate of change in velocity.
