So I need help checking my answers on "Factors that Affect Kinetic Energy Quick Check".
1. A student drops a basketball into a pool from a height of 5 meters while a friend records the approximate splash height. They want to make a bigger splash in their next trial. How can they achieve this?
A. They can use a ball that has a larger circumference
B. They can drop the same ball with less speed
C. They can use a ball with more mass ⬅️
D. They can drop the same ball from a lower height
2. Which characteristic will be affected by increasing the speed of an object from 30 mph to 40 mph?
A. weight
B. mass
C. gravitational attraction
D. kinetic energy ⬅️
4. A student drops a 350-gram rock and a 500-gram rock into a pool from a height of 8 meters. Which statement about the investigation is accurate?
A. The 500-gram rock causes a smaller splash because it has more mass
B. The 350-gram rock causes a larger splash because it has less mass
C. The 350-gram rock causes a smaller splash because it has more kinetic energy
D. The 500-gram rock causes a larger splash because it has more kinetic energy ⬅️
I skipped 3 and 5 because they both have pictures. Help!
The answers are shown in the first thing. But here to make it easy.
1) The ball with more mass
2) Kinetic energy
3) Changing the height affect mass
4) 500 g one because it has more kinetic energy
5) object X
Get one wrong commonly so teachers don't think your cheating
Hidden was right except 3
3’s answer is : does changing the speed of an object affect its kinetic energy
Ok I got 4/5 but I got the answers so nvm
Wait but now I need the answers
Of course, I would be happy to help you check your answers!
For question 1, the correct answer is C. They can use a ball with more mass. This is because when the ball has more mass, it will have more kinetic energy when it hits the water, resulting in a bigger splash. Increasing the circumference of the ball (option A) or dropping the ball with less speed (option B) wouldn't have much of an impact on the splash height. And dropping the same ball from a lower height (option D) would actually decrease the kinetic energy and therefore, the splash height.
Moving on to question 2, the correct answer is D. kinetic energy. Increasing the speed of an object will directly increase its kinetic energy. So from 30 mph to 40 mph, the kinetic energy of the object will increase.
Now for question 4, the correct answer is D. The 500-gram rock causes a larger splash because it has more kinetic energy. In this case, the mass of the rock doesn't play a significant role in determining the splash size. The kinetic energy is directly proportional to the mass of the rock, so since the 500-gram rock has more mass than the 350-gram rock, it will produce more kinetic energy when it hits the water, resulting in a larger splash.
I hope this helps! Let me know if you have any more questions or need assistance with the remaining ones.
To check your answers on the "Factors that Affect Kinetic Energy Quick Check," let's go through each question and explain how to arrive at the correct answer:
1. The question asks how to achieve a bigger splash in the next trial of dropping a basketball into a pool from a height of 5 meters. The correct answer is C. They can use a ball with more mass. Explanation: Kinetic energy is directly proportional to mass. Therefore, by increasing the mass of the ball, the kinetic energy at impact will also increase, resulting in a bigger splash.
2. The question asks which characteristic will be affected by increasing the speed of an object from 30 mph to 40 mph. The correct answer is D. kinetic energy. Explanation: Kinetic energy is directly proportional to the square of the velocity (KE = 1/2 * mass * velocity^2). As the speed increases, the kinetic energy will increase as well.
3. Since you mentioned there is a picture associated with this question and you skipped it, I am unable to provide an explanation without visual information. Please refer to the picture provided to determine the correct answer.
4. The question asks about the investigation involving dropping a 350-gram rock and a 500-gram rock into a pool from a height of 8 meters. The correct answer is D. The 500-gram rock causes a larger splash because it has more kinetic energy. Explanation: Kinetic energy is directly proportional to mass. The 500-gram rock has more mass compared to the 350-gram rock, resulting in more kinetic energy at impact and a larger splash.
5. Similarly to question 3, since there is a picture associated with this question and you skipped it, I am unable to provide an explanation without visual information. Please refer to the picture provided to determine the correct answer.
By following the explanations provided for questions 1, 2, and 4, you can assess whether your answers are correct.
