Physics IGCSE Making Measurement Quiz

What is the SI unit for measuring length?

• meter

• gram

• liter

• second

Which instrument is used to measure the mass of an object?

• thermometer

• telescope

• ruler

• scale or balance

What is the formula for calculating density?

• mass/volume

• mass x weight

• mass - volume

• density x volume

What is the purpose of using a micrometer screw gauge in measurements?

• To measure small dimensions with high precision

• To measure temperature accurately

• To measure time intervals precisely

• To measure large dimensions with low precision

How can you measure the volume of an irregularly shaped object?

• By using a ruler to measure the length, width, and height and then multiplying them together

• By asking someone else to guess the volume

• By using the water displacement method

• By estimating based on the object's appearance

What are the common units used for measuring time?

• Liters, milliliters, gallons

• Inches, feet, yards, miles

• Grams, kilograms, tons

• Seconds, minutes, hours, days, weeks, months, years

Explain the concept of parallax error in measurements.

• Parallax error is the absence of shift in the position of an object when viewed from different angles, leading to precise measurements.

• Parallax error is the fixed position of an object when viewed from different angles, leading to consistent measurements.

• Parallax error is the accurate shift in the position of an object when viewed from different angles, leading to precise measurements.

• Parallax error is the apparent shift in the position of an object when viewed from different angles, leading to inaccurate measurements.

What is the significance of using a stopwatch in physics experiments?

• To measure the time taken for an event to occur

• To count the number of atoms in a substance

• To calculate the volume of a liquid

• To determine the weight of an object

What are the precautions to be taken while using a measuring tape for length measurements?

• Hold the tape with one hand and measure with the other

• Use the measuring tape without checking for accuracy

• Ensure the tape is straight and not twisted, and hold it firmly in place.

• Let the tape dangle loosely while taking measurements
