Mass, Weight, Volume, Density

Which method is used to find the volume of an irregularly shaped object?

• Measuring its dimensions and using a formula

• Using a scale to weigh it

• Displacement method

• Using a ruler to measure its height

Which of the following best describes the difference between mass and weight?

• Mass is the amount of matter in an object, while weight is the force of gravity on the object.

• Mass is measured in newtons, while weight is measured in kilograms.

• Mass changes with location, while weight remains constant.

• Mass and weight are the same and can be used interchangeably.

Using the picture, tell me which object is the least dense and why?

• The fish because he is in the middle

• The cork because it is floating at the top of the water

• The rock because it is at the bottom

• The cork and the rock because they have the same about of atoms.

What does this tool measure?

• weight
• meters
• mass
• force

How would you measure the volume of a liquid using a graduated cylinder?

• Pour the liquid into the cylinder and read the top of the meniscus at eye level.

• Pour the liquid into the cylinder and read the bottom of the meniscus at eye level.

• Pour the liquid into the cylinder and read the side of the meniscus at eye level.

• Pour the liquid into the cylinder and read the middle of the meniscus at eye level.

Calculate the density of the cube.

• 2 g/cm³
• 4 g/cm³

Matter is anything that has

• length width and hieght
• anything that has mas and volume
• a definite shape
• energy
