Astronaut Experiment

The video explores the concept of air resistance and its effect on falling objects. It begins by explaining why objects fall at different speeds on Earth due to air resistance. The video references Commander Dave Scott's moon experiment, where a hammer and feather fell at the same rate due to the lack of atmosphere. Cartoon Sabrina replicates this experiment on Earth, demonstrating how air resistance affects falling objects. The video concludes with an experiment in a vacuum, showing that without air, objects fall at the same rate, confirming the role of air resistance.

What is the primary reason objects fall at different speeds on Earth?

• Different gravitational forces

• Air resistance

• Earth's rotation

• Object mass

Why did the hammer and feather fall at the same rate on the moon?

• The feather was heavier

• The moon has no air resistance

• The hammer was lighter

• The moon has stronger gravity

What equipment did Cartoon Sabrina use in her experiment?

• A hammer and a feather

• A vacuum chamber and a scale

• A ball, a parachute, and a spacesuit

• A ladder and a rope

In a vacuum, how do objects of different shapes fall?

• At the same speed

• The lighter object falls faster

• The heavier object falls faster

• At different speeds

What happens to the parachute in a vacuum?

• It doesn't open

• It makes the object fall faster

• It opens and slows the fall

• It causes the object to float
