Grass; the toy car will move the farthest distance.
Ice; the toy car will move the farthest distance.
Daquan observes that when a hockey puck is pushed by a hockey stick, the puck moves quickly on an icy surface, but gradually loses speed and comes to rest.
What explains Daquan's observation?
The hockey puck runs out of force.
The hockey puck is too small to keep moving.
The force of friction on the hockey puck slows it down.
The force of gravity opposes the motion of the hockey puck.
Katie stretched out her hand and dropped a rubber ball. The ball fell to the floor, and Katie’s hand stayed where it was. What happened next?
The ball gained energy from the floor and bounced above Katie’s hand.
The ball bounced back to Katie’s hand because it gained energy from the air.
The ball bounced back to Katie’s hand because the amount of energy did not change.
The ball bounced lower than Katie’s hand because some energy transferred to the floor.
Kim and Linda placed a few boxes of cereal in their carts at a grocery store. Kim’s cart moves faster than Linda’s cart when pushed with the same force.

5 in Kim’s cart and 8 in Linda’s cart
6 in Kim’s cart and 6 in Linda’s cart
7 in Kim’s cart and 4 in Linda’s cart
8 in Kim’s cart and 5 in Linda’s cart
Jacinda pushes her toy bus on a smooth tile. She then pushes it across a rough tile.
How and why will the motion of the bus change?
The bus would move faster on a smooth surface than on a rough surface because rough surfaces create more friction.
The bus would move faster on a smooth surface than on a rough surface because rough surfaces create less friction.
The bus would move faster on a rough surface than on a smooth surface because rough surfaces create more friction.
