1
Identify the base SI units for distance and time: distance is measured in meters (m) and time is measured in seconds (s).
Write the formula for acceleration: acceleration = distance/time^2.
Substitute the base SI units into the formula: acceleration = meters/seconds^2.
Simplify the expression: acceleration = m/s^2.
Thus, the derived SI unit for acceleration is m/s^2.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

SI Units

The International System of Units (SI) is the standard system of measurement used in science and engineering. It is based on seven base units, including meter (m) for distance, second (s) for time, and kilogram (kg) for mass. Derived units are formed from these base units to express other physical quantities, such as acceleration.

SI Units

Acceleration

Acceleration is defined as the rate of change of velocity per unit time. In terms of SI units, it is expressed as meters per second squared (m/s²). This indicates how much the velocity of an object changes in meters for every second squared of time, making it a crucial concept in kinematics and dynamics.

Derived Units

Derived units are combinations of base SI units that describe other physical quantities. For example, acceleration is derived from the base units of distance (meters) and time (seconds). Understanding how to derive these units is essential for converting and manipulating measurements in physics and chemistry.
