Levitating Ball & Bulb - Little Shop of Physics

The video tutorial explains the dynamics of airflow around a ball, demonstrating how air moves and creates forces that stabilize the ball in an airstream. Using Newton's third law, it shows how the ball and air interact to maintain stability. The tutorial also demonstrates using a blower to visualize these concepts and explains the importance of the ball being lightweight and round for stability in the airstream.

What principle explains the interaction between the ball and the air in the airstream?

• Newton's law of gravitation

• Newton's first law

• Newton's third law

• Newton's second law

What happens to the ball when air moves around it in the airstream?

• It falls out of the stream

• It remains stable in the stream

• It moves in a straight line

• It spins uncontrollably

What is the role of the air's curvature around the ball?

• It creates a vacuum

• It generates a stabilizing force

• It increases the ball's weight

• It decreases air pressure

Which two characteristics of the ball are crucial for maintaining stability in the airstream?

• Color and size

• Weight and shape

• Temperature and density

• Material and texture

How does the air's movement over a light bulb demonstrate the same principle as with the ball?

• It creates a lift force that stabilizes the bulb

• It causes the light bulb to heat up

• It changes the bulb's color

• It makes the light bulb spin
