Here's a breakdown:
* Velocity: Describes both the speed and direction of an object's motion.
* Acceleration: Measures how quickly the velocity of an object changes over time.
Key points about acceleration:
* Units: Acceleration is typically measured in meters per second squared (m/s²).
* Positive acceleration: Means the object is speeding up in the direction of its velocity.
* Negative acceleration: Means the object is slowing down or speeding up in the opposite direction of its velocity (also called deceleration).
* Constant acceleration: Occurs when the velocity changes by the same amount each second.
* Variable acceleration: Occurs when the velocity changes at a non-constant rate.
Examples of acceleration:
* A car speeding up from a stop.
* A ball falling due to gravity.
* A bicycle slowing down to a stop.
