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 balls would make splashes of the same size.
The size of the splash is independent of the mass of the ball.
The ball with the higher mass would make a bigger splash.
The ball with the lower mass would make a bigger splash
The ball with the higher mass would make a bigger splash.

b. How does the mass of a falling object impact the object's kinetic energy?
Mass does not impact kinetic energy.
An increase in mass causes a decrease in kinetic energy.
An increase in mass causes an increase in kinetic energy.

c. What happens to the kinetic energy of a ball when it hits
the water?
Overall, kinetic energy is gained.
All of the kinetic energy is kept by the ball.
Overall, kinetic energy is lost.
Some of the energy is transferred to the water.
Some of the energy is transferred to the water.
The ball with the higher mass would make a bigger splash.
To answer this question, we need to understand the concept of kinetic energy and how it relates to the size of the splash.
Kinetic energy is the energy an object possesses due to its motion. It is given by the formula: KE = 1/2 * m * v^2, where m represents the mass of the object and v represents its velocity.
In this scenario, the student is dropping two balls of different masses from the same height. When the balls hit the water, their potential energy is converted into kinetic energy, causing them to splash.
Now, let's examine the different options:
a. The balls would make splashes of the same size.
This option is incorrect because the mass of the balls directly affects their kinetic energy. Since the balls have different masses, their kinetic energies will also be different.
b. The size of the splash is independent of the mass of the ball.
This option is also incorrect because, as mentioned earlier, kinetic energy depends on mass. Therefore, the size of the splash will also be affected by the mass of the ball.
c. The ball with the higher mass would make a bigger splash.
This option is correct. According to the formula for kinetic energy, a larger mass will result in a greater kinetic energy. When the ball with a higher mass hits the water, it will have more kinetic energy, causing a larger splash.
d. The ball with the lower mass would make a bigger splash.
This option is incorrect. As explained previously, a higher mass results in greater kinetic energy. Therefore, a ball with lower mass would have less kinetic energy, resulting in a smaller splash.
So, in conclusion, the correct answer is: The ball with the higher mass would make a bigger splash.
