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 of the same mass from different heights. She should drop two balls of the same mass 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 with different masses from different heights. She should drop two balls with different masses from different heights.

Answer 1

To determine the effect of mass on kinetic energy, the student should conduct an experiment where she drops two balls with different masses from the same height. This method allows her to isolate the variable of mass while keeping the height and other conditions constant.

Therefore, the correct response is: She should drop two balls with different masses from the same height.
