Mini-Quiz: Mass, Weight and Gravity

by Ron Kurtus (revised 21 January 2011)

Take this Mini-Quiz to check your understanding of the lesson material.

1. If on a balance scale, m1 = 10 g, d1 = 10 cm and d2 = 5 cm, what would be the mass of m2?

100 g

20 g

5 g

2. If a known mass of 10 g is accelerated at 2 m/s, what is the mass of an object accelerated at 4 m/s on the same configuration?

5 g

10 g

20 g

3. Could a balance scale be used to measure weight?

Yes, since weight is proportional to mass

No, because weight requires a spring

It is uncertain, since no one has ever tried it

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
