Understanding Triple Beam Balance

What is the main difference between mass and weight?

• Mass changes with location, weight does not.

• Weight changes with gravity, mass does not.

• Mass is measured in newtons, weight in kilograms.

• Weight is constant throughout the universe, mass is not.

Which of the following is NOT a tool used to measure mass?

• Triple beam balance

• Electronic balance

• Spring scale

• Double pan balance

What does the first beam on a triple beam balance measure?

• Units of 1000

• Units of 100

• Units of 10

• Units of 1

What is the purpose of the zeroing or tearing knob on a triple beam balance?

• To lock the weights in place

• To calibrate the balance for different gravitational fields

• To adjust the balance to zero when the pan is empty

• To measure the weight of the object

How do you know when the triple beam balance is correctly measuring the mass of an object?

• When the weights are at the end of the beams

• When the pan is empty

• When the line is above zero

• When the line aligns with zero
