Here's a breakdown:
* Velocity: Velocity is a vector quantity that describes both the speed and direction of an object's motion. It is typically measured in meters per second (m/s).
* Final: This refers to the state of the object at the end of a considered period or event.
Key Points:
* Final velocity is a vector, meaning it has both magnitude (speed) and direction.
* It is a changing quantity, meaning it can be different at different times.
* The final velocity of an object can be positive or negative, depending on the direction of motion.
Example:
If a car accelerates from rest to a speed of 20 m/s in 5 seconds, its final velocity is 20 m/s.
Formula:
Final velocity (vf) can be calculated using the following formula:
vf = vi + at
where:
* vi = initial velocity
* a = acceleration
* t = time
Note: The formula assumes constant acceleration.
