The standard unit for acceleration is meters per second squared (m/s²).
Here's why:
* Acceleration is the rate of change of velocity.
* Velocity is measured in meters per second (m/s).
* Therefore, acceleration is measured in meters per second per second, or meters per second squared (m/s²).
This applies to both:
* Acceleration due to gravity (g): This is the specific acceleration caused by the Earth's gravitational pull near its surface. It's approximately 9.81 m/s².
* Gravitation: This is a more general term referring to the force of attraction between any two objects with mass. The acceleration due to gravitation can be calculated using Newton's Law of Universal Gravitation.
While the units are the same, it's important to note that the magnitude of acceleration due to gravity can vary slightly depending on location (altitude, latitude, local geological formations). However, the standard value of 9.81 m/s² is a good approximation for most calculations on Earth's surface.
