Mass Versus Weight: An Experiment with Galileo

In this video, Galileo conducts an experiment to explain the difference between mass and weight. He demonstrates that objects of the same shape and size fall at the same speed regardless of their weight. The video clarifies that mass is the amount of matter in an object, while weight is the effect of gravity on that matter. The experiment shows that despite different weights, objects fall at the same rate due to their shape and size. The video concludes with a review of these concepts.

Who is conducting the experiment in the video?

• Isaac Newton

• Albert Einstein

• Galileo

• Marie Curie

What is mass?

• The size of an object

• The effect of gravity on an object

• The amount of matter in an object

• The weight of an object

How does weight differ from mass?

• Weight is constant everywhere

• Weight is the same as mass

• Weight is the size of an object

• Weight is the effect of gravity on mass

If two balls of different weights are dropped from the same height, which will hit the ground first?

• The lighter ball

• It depends on the material of the balls

• The heavier ball

• Both will hit at the same time

Why do objects of the same shape and size fall at the same speed?

• Because of their shape and size

• Because of air resistance

• Because of their mass

• Because of their weight

What is the effect of gravity on an object called?

• Volume

• Density

• Weight

• Mass

What stays the same no matter where an object is?

• Weight

• Mass

• Volume

• Shape
