Here's a breakdown:
* Velocity: A measure of how fast an object is moving and in what direction.
* Acceleration: The change in velocity over a period of time.
Formula:
Acceleration (a) = (Change in Velocity (Δv)) / (Change in Time (Δt))
Units:
* Velocity is usually measured in meters per second (m/s).
* Time is usually measured in seconds (s).
* Therefore, acceleration is measured in meters per second squared (m/s²).
Types of Acceleration:
* Constant acceleration: The velocity changes at a steady rate.
* Variable acceleration: The velocity changes at an uneven rate.
Important Points:
* Acceleration can be positive, negative, or zero.
* Positive acceleration means an increase in speed.
* Negative acceleration means a decrease in speed (also called deceleration).
* Zero acceleration means the velocity is constant.
