Reading and Interpreting Data

A 5 kg bowling ball, a 0.25 kg baseball, and a 0.05 kg golf ball are dropped from a 100-meter high building.

• All objects fall at the same rate regardless of mass.
• Heavy objects fall faster than light ones.

Directions: Select the correct graph.
Mikey had two mice that were about the same age and weight. Mikey fed each of the two mice a different feed for a month. He measured how much the mice weighed every two days until the month was over. Mikey's results showed that although both mice gained weight over the month, mouse 2 gained more weight than mouse 1.Which graph below best shows these results?

• 1
• 2
• 3
