Topic 4: A beam balance will give you a different mass reading on the moon from that on Earth. A beam balance, however, will give you the same reading. Explain why.
The picture above is a picture of a spring balance . The spring balance measures weight in Newtons . The spring balance measures WEIGHT by the gravitational pull from the earth , since the gravitational pull on earth and the moon is different , the weight measured by the spring balance would also be different .
The picture above is a picture of a beam balance . Unlike the spring balance , the beam balance measures MASS and mass is constant . The beam balance does not depend on the gravitational pull from the earth , therefore , the beam balance will give you the same reading on earth and on the moon .
