A student wants to determine the effect of mass on kinetic energy. She will drop two balls of the same size into a pool of water. Which investigation method should the student use?(1 point) Responses She should drop two balls of the same mass from the same height. She should drop two balls of the same mass from the same height. She should drop two balls with different masses from different heights. She should drop two balls with different masses from different heights. She should drop two balls with different masses from the same height. She should drop two balls with different masses from the same height. She should drop two balls of the same mass from different heights.

Answer 1

To determine the effect of mass on kinetic energy, the student should conduct the experiment with the same height and different masses. This way, she can isolate the variable of mass and observe how it affects the kinetic energy when both balls are dropped from the same height.

Therefore, the best investigation method is:

She should drop two balls with different masses from the same height.
