OPEN ENDED QUESTION

Imagine that you are out grocery shopping and are pushing a cart. You push the cart at the same speed the entire time, but fill it up with groceries as you go. When would the cart have more kinetic energy - when it is empty or full? Why?

Evaluate responses using AI:

OFF

Answer explanation

The full cart would have more KE because it has more mass than the empty cart. Both carts are moving at the same speed, so the only difference is mass.

It's wintertime and you are sledding down a steep hill. When do you have more KE, at the top when you start your slide or at the bottom as you finish your slide? Why?

Evaluate responses using AI:

OFF

Answer explanation

You have more KE at the bottom because you are moving fastest at the bottom of the hill. This is because you pick up speed as you travel down the hill. Your mass stays the same, so it doesn't affect the amount of KE.

OPEN ENDED QUESTION

You and your friends are sledding on a four-person sled. In the middle of your run, one of you falls off. Does the KE of the sled increase, decrease, or stay the same right after that happens? Why?

Evaluate responses using AI:

OFF

Answer explanation

The KE decreases because the sled lost the mass of one person. Less mass means that it has less KE now.
