What is the difference between velocity and acceleration? a. velocity describes an object's position and acceleration describes how fast it moves. b. velocity is how fast an object moves and acceleration is the rate of change in velocity. c. velocity is used to determine the magnitude of force acting on an object, and acceleration isn't. d. velocity is a time-dependent property of an object, while acceleration is not.

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.

if you think your dog may have been exposed to a toxin, the best thing to do is to check the label of the item you think your pet ingested. read the information about toxicity. often, but not always, the information on packaging regarding children is relevant to dogs and some manufacturers even discuss dog toxicity. if there is an 800 number on the package – call them! it’s also recommended that you call your veterinarian to confirm the recommendations. if you go to your veterinarian, take all packaging and any information you have on the product.
