Step 1:I'll solve this step by step with precise LaTeX formatting:
Step 2:: Understand the Definition of Acceleration
Acceleration is the rate of change of velocity with respect to time. It describes how quickly an object's velocity is changing.
Step 3:: Analyze the Units of Acceleration
\text{Acceleration} = \frac{\text{velocity}}{\text{time}} = \frac{\text{meters per second}}{\text{second}} = \text{meters per second squared}
The standard unit of acceleration is the change in velocity per unit of time. This means:
Step 4:: Evaluate Each Option
Meters per second squared: $$\text{m/s}^{2}$$ - This matches the correct definition of acceleration
A. Foot-pounds: This is a unit of work or energy, not acceleration B. Kilograms: This is a unit of mass, not acceleration C. D. Newtons: This is a unit of force, not acceleration
Step 5:: Confirm the Correct Unit
The correct unit for acceleration is meters per second squared, which represents the change in velocity over time.
Final Answer
Meters per second squared
