Distance, Displacement, Speed, and Velocity Quiz

Which of the following scenarios best illustrates the fundamental difference between distance and displacement?

• A student walking in a perfect square path
• A car driving straight down a highway
• A boat sailing around an island
• A roller coaster moving through a complex track

If an object travels 100 m north, then 75 m south, what is its total displacement?

• 175 m
• 25 m north
• 0 m
• 125 m

Which mathematical relationship best describes the connection between speed and velocity?

• Speed is always greater than velocity
• Velocity is speed with directional information
• Speed and velocity are completely unrelated
• Velocity is a type of acceleration

An object moves 240 m in 12 seconds. What is its average speed and what critical information is missing?

• 20 m/s, direction
• 20 m/s, acceleration
• 20 m/s, time
• 20 m/s, mass

Why is displacement considered a vector quantity while distance is a scalar quantity?

• Displacement includes directional information
• Displacement is always larger
• Distance can be measured in multiple units
• Vectors are always more complex

In a circular motion at constant speed, what remains true about velocity?

• Velocity is constant
• Velocity is always changing
• Speed remains zero
• Direction is irrelevant

Which scenario demonstrates zero displacement?

• Walking 100 m north
• Running in a complete circle
• Driving 50 km east
• Jumping vertically

The average velocity formula (Δx/Δt) specifically requires what two critical components?

• Total distance and total time
• Displacement and total time
• Speed and acceleration
• Mass and direction

What distinguishes instantaneous velocity from average velocity?

• Instantaneous velocity measures speed at a specific moment
• Average velocity includes acceleration
• Instantaneous velocity is always zero
• Average velocity cannot be calculated

A vector quantity must include:

• Only magnitude
• Only direction
• Both magnitude and direction
• Neither magnitude nor direction
