The Science of Density

The video tutorial compares a golf ball and a ping-pong ball, explaining that a golf ball would hurt more due to its higher density. Density is defined as the amount of matter in a given volume, and the video demonstrates how to calculate it using the formula: density equals mass divided by volume. An example is provided using a box filled with stones to illustrate the calculation process.

Which ball would cause more pain if it hit you, and why?

• Ping-pong ball, because it is lighter

• Golf ball, because it is smaller

• Golf ball, because it is denser

• Ping-pong ball, because it is larger

What does density measure?

• The color of an object

• The weight of an object

• The size of an object

• The amount of matter in a given volume

How can you calculate the density of an object?

• By adding mass and volume

• By dividing mass by volume

• By multiplying mass and volume

• By dividing volume by mass

In the example provided, what is the volume of the box?

• 1,575 cubic centimeters

• 3,000 grams

• 3,000 cubic centimeters

• 1,575 grams

What is the density of the box filled with stones?

• 3.0 grams per cubic centimeter

• 2.0 grams per cubic centimeter

• 1.9 grams per cubic centimeter

• 1.5 grams per cubic centimeter
