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?
(1 point)
Responses
The ball with the higher mass would make a bigger splash.
The ball with the higher mass would make a bigger splash.
The size of the splash is independent of the mass of the ball.
The size of the splash is independent of the mass of the ball.
The balls would make splashes of the same size.
The balls would make splashes of the same size.
The ball with the lower mass would make a bigger splash.
The ball with the lower mass would make a bigger splash.
Question 2
b. How does the mass of a falling object impact the object's kinetic energy?(1 point)
Responses
Mass does not impact kinetic energy.
Mass does not impact kinetic energy.
An increase in mass causes a decrease in kinetic energy.
An increase in mass causes a decrease in kinetic energy.
An increase in mass causes an increase in kinetic energy.
An increase in mass causes an increase in kinetic energy.
A decrease in mass causes an increase in kinetic energy.
A decrease in mass causes an increase in kinetic energy.
Question 3
c. What happens to the kinetic energy of a ball when it hits the water?(1 point)
Responses
Some of the energy is transferred to the water.
Some of the energy is transferred to the water.
All of the kinetic energy is kept by the ball.
