Understanding Speed and Velocity Concepts

What is the definition of speed?

• Distance divided by time

• Time divided by distance

• Distance multiplied by time

• Time plus distance

A car travels 100 meters in 5 seconds. What is its speed?

• 5 m/s

• 10 m/s

• 20 m/s

• 50 m/s

What are the standard units for speed in the metric system?

• Miles per hour

• Kilometers per hour

• Meters per second

• Feet per second

If a car's speed is 20 meters per second, what does this mean?

• The car travels 20 meters in 20 seconds

• The car travels 1 meter in 20 seconds

• The car travels 20 meters every second

• The car travels 100 meters in 5 seconds

What does the calculated speed represent if the car's speed varies throughout the journey but covers a total distance in a total time?

• Instantaneous speed

• Maximum speed

• Minimum speed

• Average speed

In a distance-time graph, which axis typically represents time?

• The vertical axis

• The horizontal axis

• Both axes

• Neither axis

What type of line is formed on a distance-time graph when an object moves at a steady rate?

• A curved line

• A zigzag line

• A straight line

• A dotted line

What does the slope of a distance-time graph represent?

• Acceleration

• Force

• Speed

• Time

How can you tell if an object is moving faster by looking at its distance-time graph?

• The line is horizontal

• The line is less steep

• The line is steeper

• The line is curved

What is the key difference between speed and velocity?

• Speed includes direction

• Velocity includes direction

• Speed is a vector quantity

• Velocity is a scalar quantity
