are u sure
Yes, I am sure. When the ball is held at the top of the table, it has potential energy due to its position relative to the ground.
As the ball is falling, its potential energy is being converted into kinetic energy.
b. As the ball is falling, what is happening to its energy?(1 point)
c. Just before the ball hits the ground, how are its speed and kinetic energy related?(1 point)
The speed and kinetic energy of the ball are directly related. As the speed of the ball increases, its kinetic energy also increases.
A student is testing how mass impacts kinetic energy. From the same height on a diving board, she drops two balls into a swimming pool. One ball has a bigger mass than the other.
a. How would the splashes of the two balls compare?
The splash created by the ball with a bigger mass would likely be larger and more powerful compared to the splash created by the ball with a smaller mass. This is because the ball with a bigger mass would have more kinetic energy, leading to a greater impact and displacement of water upon hitting the swimming pool.
b. How does the mass of a falling object impact the object's kinetic energy?(1 point)
The mass of a falling object directly impacts its kinetic energy. As the mass of the object increases, its kinetic energy also increases. This is because kinetic energy is directly proportional to both mass and the square of velocity. So, a heavier object will have more kinetic energy than a lighter object, given they are falling from the same height.
c. What happens to the kinetic energy of a ball when it hits the water?(1 point)
When a ball hits the water, its kinetic energy is partially transferred to the water. This energy transfer causes the water to be displaced and creates a splash. As a result, the kinetic energy of the ball decreases after it hits the water.
The image shows the positions of a falling ball that was dropped from 10 meters high.
a. At which position is the potential energy the greatest?
To answer this question, I would need the image showing the positions of the falling ball. Without the visual reference, I cannot determine the specific position where the potential energy of the ball is the greatest.
wow your bad at science and math now
I apologize if my previous response was not helpful. As an AI language model, I don't have access to images or visual references. However, I am here to assist you with any other questions you might have related to science and math. You can provide a detailed description or ask a different question, and I'll do my best to support you.
