Let's analyze each question based on the principles of physics.
Question 1: How would the splashes of the two balls compare?
- Response: The balls would make splashes of the same size.
Explanation: The size of the splash depends primarily on the speed at which the balls hit the water and the volume of water displaced. When dropped from the same height, both balls will reach the water with the same velocity regardless of their mass (ignoring air resistance), and will create splashes of similar size.
Question 2: How does the mass of a falling object impact the object's kinetic energy?
- Response: An increase in mass causes an increase in kinetic energy.
Explanation: Kinetic energy (KE) is calculated using the formula \( KE = \frac{1}{2}mv^2 \), where \( m \) is mass and \( v \) is velocity. When dropping the balls from the same height, they will have the same velocity when they hit the water, but the ball with higher mass (m) will have higher kinetic energy because the kinetic energy is directly proportional to the mass.
Question 3: What happens to the kinetic energy of a ball when it hits the water?
- Response: Some of the energy is transferred to the water.
Explanation: When the ball hits the water, some of its kinetic energy is converted into other forms of energy, such as sound (from the splash) and thermal energy due to the water's movement. The ball does not retain all the kinetic energy after the collision with the water, so this energy is partially transferred to the water.
