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.

Answer 1

To determine the effect of mass on kinetic energy, the student should drop two balls with different masses from the same height. This method allows her to isolate the variable of mass while keeping the height (and therefore the potential energy at the point of release) consistent, enabling an accurate measurement of the resulting kinetic energy when the balls hit the water.

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