Here's a breakdown:
* Speed: How fast an object is moving.
* Acceleration: The rate at which an object's speed changes over time.
Key Points:
* Acceleration can be positive or negative:
* Positive acceleration: The object's speed is increasing.
* Negative acceleration (deceleration): The object's speed is decreasing.
* Acceleration can also be zero: This means the object's speed is constant (not changing).
Units of Acceleration:
Acceleration is typically measured in units of meters per second squared (m/s²). This means that the object's speed is changing by a certain number of meters per second, every second.
Example:
If a car accelerates at a rate of 5 m/s², this means that its speed is increasing by 5 meters per second every second.
