Understanding Motion and Measurement

What is measurement?

• Measurement is the act of comparing objects without any numerical values.

• Measurement is the process of estimating values without using units.

• Measurement is the quantification of physical properties using defined units.

• Measurement refers to the subjective interpretation of physical properties.

What are standard units of measurement?

• Liters for temperature

• Pounds for distance

• Examples include meters for length, kilograms for mass, and seconds for time.

• Hours for volume

Name one standard unit used for measuring length.

• second

• meter

• gram

• liter

What is linear motion?

• Linear motion is the movement of an object in a straight line.

• Linear motion refers to the oscillation of an object back and forth.

• Linear motion is the movement of an object in a zigzag pattern.

• Linear motion is the movement of an object in a circular path.

Give an example of linear motion.

• A plane taking off from a runway.

• A car driving down a straight road.

• A bicycle going around a circular track.

• A ball rolling down a hill.

What is circular motion?

• Oscillatory motion back and forth.

• Random movement in multiple directions.

• Circular motion is the movement of an object along a circular path.

• Linear motion along a straight line.

Provide an example of circular motion.

• A bicycle riding in a straight line.

• A plane flying at a constant altitude.

• A boat drifting in a calm lake.

• A car driving around a circular track.

What is oscillatory motion?

• A single movement in one direction without returning.

• A type of circular motion around a fixed point.

• Oscillatory motion is the repetitive back-and-forth movement of an object around a central point.

• A random movement with no specific pattern.

Describe a characteristic of oscillatory motion.

• Repetitive back-and-forth movement around a central point.

• A single, non-repeating motion.

• Movement that only occurs in one direction.

• Constant speed in a straight line.

Can you name an example of oscillatory motion?

• The swinging of a pendulum

• The rotation of a wheel

• The movement of a car in a straight line

• The flow of water in a river
