Car #6 will lose energy and car #39 will gain energy.
Car #6 will gain energy and car #39 will lose energy.
Car #6 will gain energy and car #39 will gain energy.
Seymour's toy cart was sitting flat on the floor. Seymour started throwing his toys into it. The cart started to roll away from Seymour. What made the cart start to move?
Seymour pushed on the cart with a non-contact force.
The toys gave their energy of motion to the cart.
The cart became too light to stay in one place.
The toys added to the force of gravity pulling the cart down.
Fitz is riding his bike on a flat trail. The faster Fitz pedals, the faster the bike moves. He can also use the handlebars to change the bike's direction. Which of these would definitely increase Fitz's energy of motion?
Fitz uses the handlebars to change directions.
Fitz stops pedaling.
Fitz starts pedaling faster.
Fitz starts pedaling slower.
Jamal has two identical metal cans. He lifts his foot in the air and slowly brings it down to put force on one of the metal cans. After Jamal lifts his foot back into the air, the metal can is bent in the middle. Jamal is going to use his foot in the same way to put force on the second metal can. What will most likely happen if Jamal moves his foot faster as he brings it down on the second metal can?
The second metal can will become shaped like the top of Jamal's foot.
The second metal can will not change shape.
The second metal can will become less bent than the first metal can.
The second metal can will become more bent than the first metal can.
Two coyotes that are the same weight are running across the snow. Which of these is true?
The coyote that is running the slowest has the most energy of motion.
The coyote that is running the fastest has the most energy of motion.
The coyote that is in front definitely has more energy of motion.
The coyotes have the same energy of motion, even if they are running at different speeds.
A ferret took a running jump and landed on a skateboard. Before the ferret landed on it, the skateboard was not moving. When the ferret landed on the skateboard, it started moving. Some of the ferret's _________________ was transferred to the skateboard. The skateboard moved more quickly than the ferret had been moving when he landed on it
