Imagine James is racing his cart down a track, and it's picking up speed! What can we infer about James's cart’s kinetic (or motion) energy in this thrilling situation?

• We can infer that the cart’s kinetic (or motion) energy is increasing.

• We can observe that the cart’s kinetic (or motion) energy is increasing.

• We can see that the cart’s kinetic (or motion) energy is increasing.

• We cannot say anything about the cart’s kinetic (or motion) energy.

Imagine Samuel and Ethan are racing their toy carts on a track. Based on the statement from the previous question, what can we infer about Samuel's cart's kinetic (or motion) energy between 2 seconds and 4 seconds?

• Samuel's cart’s kinetic (or motion) energy is increasing because the speed of the cart is increasing.

• Samuel's cart’s kinetic (or motion) energy is decreasing because the cart’s speed is increasing.

• We cannot infer anything about Samuel's cart’s kinetic (or motion) energy because we cannot see its energy directly.

• Samuel's cart’s kinetic (or motion) energy is the same as the cart’s speed.

In a thrilling physics experiment, Luna and Benjamin are observing two carts on a track. Cart A, driven by Luna, zooms towards a stationary Cart B, which Benjamin is watching closely. After the collision, Cart A slows down while Cart B speeds up. What magical transformation happens to the kinetic energy between Cart A and Cart B during this exciting collision?

• The energy remains the same in cart A, it has nothing to do with the energy in cart B.

• The energy is converted from cart A to cart B

• The energy is transferred from cart A to cart B.

• We cannot infer anything about the energy of the carts, only their speed.
