In science class, students roll four balls down a slope and record this data. Ball Race Ball Distance Time Ball A 15 meters 15 seconds Ball B 15 meters 12 seconds Ball C 15 meters 16 seconds Ball D 15 meters 10 seconds Which ball is slowest?

• Ball A
• Ball B
• Ball C
• Ball D

Liam is practicing soccer with his team. He puts two balls on the ground. In Figure 1, the two balls are labeled Ball X and Ball Y. When Liam kicks Ball X, it moves across the field until it hits Ball Y. Then Ball Y starts to move. After it rolls for a while, Ball Y stops. Liam then lines up three soccer balls. They are shown in Figure 2 as Ball X, Ball Y and Ball Z. When he kicks Ball X, it moves and hits Ball Y. Then Ball X slows down and Ball Y moves. When Ball Y hits Ball Z, Ball Y slows down and Ball Z starts to move. After Ball Z moves for a while, it stops. What evidence suggests that energy was transferred to Ball Z?

• Ball Z was moving faster than Ball X and Ball Y.
• Ball Z was at rest but started moving when Ball Y hit it.
• Ball Z was moving quickly but slowed down when Ball Y hit it.
• Ball Z was moving slowly but stopped when Ball Y hit it.

Students investigate how the force of the wind affects the movement of equal-sized balls that have different masses. Ball Mass (grams) 1 30 2 20 3 10 4 40 As students watch, a wind blows equally on all of the balls. When the wind stops, students draw a picture of their results. Based on the results, what should the students conclude?

• Balls move easily when their mass is higher.
• Balls move farther when the wind speed is lower.
• Balls move farther when their mass is lower.
• Balls move quickly when their size is larger.
