Responses
Joaquin and Susanna stop pushing the cart.
Joaquin and Susanna stop pushing the cart.
Joaquin and Susanna transfer energy to the cart.
Joaquin and Susanna transfer energy to the cart.
The ground transfers energy to the cart.
The ground transfers energy to the cart.
Gravity makes the cart move.
The correct answer is: Joaquin and Susanna transfer energy to the cart.
In sections A, B, C, and D, the cart is moved by Joaquin and Susanna transferring energy to the cart, and the ground transferring energy to the cart. Additionally, gravity plays a role in making the cart move.
The correct answer is "Joaquin and Susanna transfer energy to the cart." In order to understand why this is the correct answer, let's break down the options and analyze each one.
1. "Joaquin and Susanna stop pushing the cart":
This option suggests that the cart is moving because Joaquin and Susanna have stopped pushing it. However, this doesn't explain why the cart started moving in the first place. So, this is not the correct answer.
2. "The ground transfers energy to the cart":
Although the ground does exert a force on the cart, it is not the primary cause of the cart's movement. The ground provides a surface for the cart to move on, but it doesn't actively transfer energy to the cart. Therefore, this option is not the correct answer.
3. "Gravity makes the cart move":
Gravity does play a role in the cart's movement, but it alone is not the main cause. Gravity provides the force that pulls the cart downwards, but for the cart to actually move, there needs to be a force in the opposite direction. So, gravity alone cannot explain the cart's movement. Hence, this option is not the correct answer.
4. "Joaquin and Susanna transfer energy to the cart":
This option correctly identifies that Joaquin and Susanna are the ones responsible for transferring energy to the cart, causing it to move. By pushing the cart, they apply a force which results in the transfer of energy to the cart, enabling it to move. This is the correct answer.
To summarize, the correct choice is "Joaquin and Susanna transfer energy to the cart" because they are the ones applying the force that causes the cart to move.
