For example if the ball is dropped into water‚ its energy will affect the water‚ causing some amount to splashed out. When the ball is released from a height‚ its initial potential energy combined with the gravitational energy form a kinetic energy‚ which transmitted to the water. So I will investigate the relationship of drop height of the ball and the amount of water splashed out. Research question: How does the volume of water splashed out depend on drop height of the ball? Explanation for controlled
