What is the main topic of the video?

• The difference between power and work

• The difference between force and energy

• The difference between mass and weight

• The difference between speed and velocity

Which of the following is a scalar quantity?

• Velocity

• Acceleration

• Speed

• Force

How is speed defined in the video?

• Distance covered in a specific direction

• Distance covered over time

• Change in velocity over time

• Force applied over a distance

What additional information does velocity provide that speed does not?

• Magnitude

• Time

• Direction

• Distance

In the example, what is the speed of the bicycle ride to the park?

• 15 kilometers per hour

• 20 kilometers per hour

• 5 kilometers per hour

• 10 kilometers per hour

What is the velocity if you return to the starting point after moving in a circle?

• 10 km/h

• 5 km/h

• 0 km/h

• 15 km/h

Why is the velocity zero when you return to the starting point?

• Because there is no directional gain

• Because the speed is zero

• Because the time is zero

• Because the distance is zero

What is the average velocity if you walk in a square and return to the starting point?

• 10 km/h

• 5 km/h

• 15 km/h

• 0 km/h

What does the narrator offer to explain in another video if requested?

• The difference between mass and weight

• The difference between distance and displacement

• The difference between force and energy

• The difference between power and work
