MCQs on Measurement of Length and Motion

Which of the following is a traditional Indian unit of length?

• Millimetre

• Handspan

• Metre

• Kilometre

The need for SI units arose because:

• Traditional units were very accurate

• Body-based measurements varied from person to person

• SI units are larger than traditional units

• Only scientists used SI units

The SI unit of length is:

• Centimetre

• Foot

• Metre

• Kilometre

1 kilometre is equal to:

• 100 m

• 1000 m

• 100 cm

• 10,000 m

3 cm = ? mm

• 0.3 mm

• 30 mm

• 300 mm

• 3 mm

To convert from a smaller unit to a larger unit, we:

• Multiply

• Divide

• Subtract

• Add

The smallest length that can be measured using a geometry box ruler is:

• 1 cm

• 1 mm

• 0.1 mm

• 1 m

Which measuring tape is best suited to measure curved lines like a bottle rim?

• Geometry box ruler

• Steel tape

• Flexible fabric tape

• Wooden scale

When using a broken scale (zero mark missing), the correct method is to:

• Estimate length by eye

• Start from any clear mark and subtract the difference

• Start from the broken end directly

• Not measure at all

While reading a scale, the correct position of the eye should be:

• From the left side

• From the right side

• Exactly above the mark

• From any convenient angle
