Let’s design a simple quiz to evaluate understanding of key concepts and processes in physics. The quiz should include a variety of question types, including multiple choice, true/false, short answer, and calculation problems. Ensure the questions are balanced across different areas of physics to avoid bias. Focus the quiz topics on mechanics, electricity and magnetism, and thermodynamics.
Here’s a sample quiz with questions centered on mechanics, electricity and magnetism, and thermodynamics:
### Quiz Instructions
Each question is worth 1 point unless otherwise stated. There’s a total of 10 points.
### Multiple Choice
1. **Which of the following formulas represent’s Newton’s second law of motion?**
- a. ( F = ma )
- b. ( F = mg )
- c. ( F = frac{m}{a} )
- d. ( F = ma^2 )
2. **What’s the formula for calculating the speed of light in vacuum?**
- a. ( c = E imes m )
- b. ( c = frac{v}{f} )
- c. ( c = f imes lambda )
- d. ( c = f imes lambda^2 )
### True/False
3. ( f imes lambda ) equals speed. (True/false)
4. Speed is a scalar quantity. (True/false)
### Short Answer
5. Write the formula for calculating the frequency of a wave.
6. Write the formula for calculating the current in a circuit.
### Calculation Problems
7. A pack of milk weighs 2 kg. What’s the force it exerts on the earth?
8. List the formulas used in calculating the circumference of a circle.
### Extra Credit (worth 2 points)
9. The sun emits 3.86 x 10^24 joules of energy every second. Calculate the amount of energy emitted in one year.
10. The Milky Way galaxy has a circumference of about 200,000 light-years. Calculate its diameter in kilometers.
### Quiz Key
1. a
2. c
3. true
4. true
5. ( f = frac{v}{lambda} )
6. ( I = frac{voltage}{resistance} )
7. ( F = 2kg imes 9.8ms^-2 = 19.6N )
8. ( C = pi d ) or ( C = 2 pi r )
9. ( E = 3.86 imes 10^24 imes 60 imes 60 imes 24 imes 365 = ) your total
10. ( d = 200,000 imes 9.46 imes 10^12 = ) your total
### [solved] Here’s what grading looks like
Percentage ( imes frac{100}{10} ) = total grade
### Hints
Use multiple choice answers to aid in calculations.
