Here's a breakdown:
* Velocity: Velocity is a measure of how fast an object is moving and in what direction. It's a vector quantity, meaning it has both magnitude (speed) and direction.
* Acceleration: Acceleration is the rate at which an object's velocity changes over time. It's also a vector quantity.
Calculating Acceleration:
You can calculate acceleration using the following formula:
Acceleration (a) = (Final Velocity (vf) - Initial Velocity (vi)) / Time (t)
Example:
Let's say a car starts from rest (initial velocity = 0 m/s) and reaches a speed of 20 m/s in 5 seconds.
* Initial Velocity (vi) = 0 m/s
* Final Velocity (vf) = 20 m/s
* Time (t) = 5 seconds
Therefore, the acceleration of the car is:
* a = (20 m/s - 0 m/s) / 5 s = 4 m/s²
This means the car's velocity is increasing by 4 meters per second every second.
