Physics Quiz for Grade 10 Students

What is the scientific method?

• A way to guess scientific outcomes

• A method to memorize scientific facts

• A process that ensures theories are thoroughly tested

• A technique to avoid conducting experiments

What is the difference between accuracy and precision in measurements?

• Accuracy and precision are not important in scientific experiments

• Accuracy refers to how close a measurement is to the true value, while precision refers to the consistency of repeated measurements

• Accuracy refers to the consistency of repeated measurements, while precision refers to how close a measurement is to the true value

• Accuracy and precision mean the same thing in measurements

What is the term used to describe errors that have no pattern or bias and may be above or below the true value?

• Systematic errors

• Random errors

• Instrument errors

• Zero errors

Why is it important to express the uncertainty in measurements?

• To hide mistakes in the measurements

• To understand the limitations of the data collected

• To confuse other scientists

• To make the experiment seem more complex

What is the purpose of writing scientific reports?

• To communicate experimental procedures and results clearly

• To make the experiment more confusing

• To keep the data private

• To avoid sharing scientific findings

Which term refers to the quality of being exact and the degree to which repeated measurements under the same conditions give the same value?

• Precision

• Accuracy

• Significance

• Uncertainty

What is the term used to describe errors caused by a bias in measurement and which show a trend?

• Systematic errors

• Random errors

• Zero errors

• Instrument errors

What is the importance of selecting an instrument with appropriate precision?

• To ensure accurate and reliable measurements

• To make the experiment more complicated

• To confuse the students

• To increase the cost of the experiment

What is the term used to describe the number of significant figures used in a reading, which should be appropriate to the precision of the measuring instrument?

• Significance

• Accuracy

• Precision

• Uncertainty

What is the process that ensures a rigorous, evidence-based structure where only ideas that have been carefully tested are accepted as scientific theory?

• Peer review

• Scientific method

• Data collection

• Hypothesis testing
