Length, Time, and Motion Quiz

What is the primary purpose of a ruler?

• To measure time intervals
• To measure the length of objects
• To calculate volume
• To determine speed

What is the primary use of a ruler in scientific measurements?

• To measure mass
• To measure length between 1mm and 1m
• To measure temperature
• To measure volume

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

• Using a ruler
• By weighing it
• Using a measuring cylinder filled with water
• Using a micrometer screw gauge

What does the rise in water level represent when measuring the volume of an irregular object?

• The object's mass
• The object's density
• The object's volume
• The object's surface area

Which instrument is used to measure very small distances that a ruler cannot measure?

• Thermometer
• Barometer
• Micrometer screw gauge
• Voltmeter

What is the relationship between speed, distance, and time?

• Speed = Distance × Time
• Speed = Distance ÷ Time
• Speed = Time ÷ Distance
• Speed = Distance + Time

What does it mean if an object's speed is changing?

• It has constant velocity
• It is accelerating
• It has zero momentum
• It is at rest

Which of the following is true about the acceleration of free fall near Earth?

• It varies greatly with altitude
• It is zero
• It is constant
• It depends on the mass of the falling object

Which of the following is NOT a common unit for measuring distance?

• mm
• cm
• m
• ms

How is velocity different from speed?

• Velocity includes direction
• Velocity is always faster than speed
• Velocity is measured in different units
• Velocity only applies to objects in space
