Speed and Velocity Explained! - what’s the difference?!

This video tutorial explains the concepts of speed and velocity, highlighting their similarities and differences. Speed is defined as the distance an object travels per unit of time, while velocity includes both speed and direction. The video provides examples to illustrate these concepts, emphasizing that velocity requires a specified direction, unlike speed. The tutorial also revisits related concepts of distance and displacement, encouraging viewers to review previous materials if needed.

What is the primary difference between speed and velocity?

• Velocity is always greater than speed.

• Speed is measured in meters, velocity in seconds.

• Velocity includes direction, speed does not.

• Speed includes direction, velocity does not.

Which of the following is a correct unit for speed?

• Meters per second

• Seconds per meter

• Miles per hour squared

• Kilometers per hour per second

If a car travels 60 miles in 2 hours, what is its speed?

• 30 miles per hour

• 60 miles per hour

• 120 miles per hour

• 15 miles per hour

How does velocity differ from speed in terms of direction?

• Velocity does not require direction.

• Both speed and velocity require direction.

• Speed requires direction, velocity does not.

• Velocity requires direction, speed does not.

In the example where Elena rides her bike, what makes her movement a velocity?

• The direction is specified.

• The speed is constant.

• The time is measured in seconds.

• The distance is measured in meters.
