Question
What values are needed to calculate speed?
- A. distance and momentum
- B. distance and time
- C. mass and time
- D. mass and momentum
Solution
Break Down the Problem
- Identify the factors that are needed to calculate speed.
Relevant Concepts
- Speed is defined by the formula: This means that speed requires two key values: distance and time.
Analysis and Detail
- Let's consider the options:
- A) Distance and momentum: Momentum is not relevant for calculating speed.
- B) Distance and time: This pair is essential as per the definition above.
- C) Mass and time: Mass is unrelated to the calculation of speed.
- D) Mass and momentum: Neither of these variables is needed for speed calculation.
Verify and Summarize
- The key takeaway is that the calculation of speed directly depends on distance and time.
Final Answer
The correct answer is B) distance and time.
